We already know that the slope of a line is rise over run
or y1-y2/x1-x2
But that only gives us the slope
What if we want to have an equation that shows what points it passes through as well
Well, that's basically what slope-intercept is.
We can use this simple formula (simple because there's much more complicated formulas)
y=mx+b where y equals the y coordinate, x equals the x coordinate, m equals the slope, and b is the y-intercept.
As an example, I'll do the first one for you.
y=mx+b
Plug in what we know
y=1x+4
You can simplify this down to
y=x+4, since 1 is identity property.
Then, you make up what x is, and your like "x is 0", if x=0, then y=4, so it'll work like that, but I'm pretty sure you don't have to show that.
And as a treat, I'll do the second one as an example:
y=mx+b
Plug in what we know
y=2x+(-2)
Simplify
y=2x-2
Same thing here, you make up what x is, and your like "x is 0", if x=0, then y=4, so it'll work like that, but I'm pretty sure you don't have to show that.
Hope this helps, let me know if you have any questions,

Find the 16th term of the arithmetic sequence whose common difference is d=6 and whose first term is a 1=3
Answers
Answer:
93
Step-by-step explanation:
This question is on Arithmetic sequence, and we can find the 16th term using the Arithmetic sequence formula below;
aₙ= a₁ + (n-1)d
Where n= nth term in that particular sequence.
n₁= first term in the particular sequence.
d= common sequence between the terms.
Given:
d=6
a₁ =3.
Using the formula above,
a₁₆= 3 + (16-1)6
= 3+(15)6
=3+90
=93
Hence, the the 16th term of the arithmetic sequence is 93

Diego was asked to plot these points: (−50,0) ( − 50 , 0 ) , (150,100) ( 150 , 100 ) , (200,−100) ( 200 , − 100 ) , (350,50) ( 350 , 50 ) , (−250,0) ( − 250 , 0 ) . What interval could he use for each axis?
Answers
Answer:
We have the points:
(-50, 0)
(150, 100)
(200, -100)
(350, 50)
(-250, 0)
First, we need to find the smallest and largest values of the x-component.
The smallest value is x = -250
The largest value is x = 350
Then the interval that we choose for the x-axis should include these two values (so we can plot the points)
Then we need to use, at least, the interval [-250, 350] (A interval that is a little bit larger than that will be easier to read, but that is the minimum he needs to do the plot)
Now let's do the same with the values of the y-components.
The smallest value is y = - 100
The largest value is y = 100
Then the vertical interval should be [-100, 100] or a little bit larger, like in the horizontal case.
We also can see that the values of x and y seem to jump in multiples of 50, then each unit of the grid could represent 50 units, so it is easier to plot. (These are also called intervals, and also theses will depend on each individual axis, but in this case we could use the same for both of them, because it works well for both axis)
Use an interval of 50, because all the
coordinates involve points that are greater than 50 and multiples of 50.
If you multiply or divide both sides of an inequality by a negative number, you must __________ the inequality sign.

Answer:

Step-by-step explanation:
When you multiply both sides by a negative value you make the side that is greater have a larger negative number, which actually means it is now less than the other side. This is why you mathematically have to flip the sign whenever you multiply by a negative number.

Find the domain and range of each relation. Then determine if the relation is a function. D={-2, -1, 3, 5}, R={-7 ,0 ,4} Function?
Answers
Answer:
[tex]D = \{-2,-1,3,5\}[/tex] -- Domain
[tex]R = \{-7,0,4\}[/tex] -- Range
It is a function
Step-by-step explanation:
Given
[tex]D = \{-2,-1,3,5\}[/tex]
[tex]R = \{-7,0,4\}[/tex]
Required
State the domain and range
Determine if the relation is a function
From the question, we have the domain and range as:
[tex]D = \{-2,-1,3,5\}[/tex] -- Domain
[tex]R = \{-7,0,4\}[/tex] -- Range
Next, is to determine if the relation is a function or not.
Yes, it is a function.
The number of elements in the domain is 4
The number of elements in the range is 3
When the domain has more elements than the range, this is called a many-to-one function, and it is a valid type of function.

Sheleah and her family are planning a trip from Los Angeles, California to Melbourne, Australia. While booking her family's plane tickets, she notices on the itinerary that the airline is offering a sixteen hour straight flight from Los Angeles to Melbourne on a Boeing 747-8 Intercontinental Jet. In an effort to learn more about the capabilities of the Jet, Sheleah does a little research and stumbles upon the following graph and facts about the Jet's gasoline consumption.
GRAPH IN SCREENSHOT
The Boeing 747-8 Intercontinental Jet can carry approximately 422,000 gallons of gasoline, making it possible for the jet to travel 14,430 kilometers before needing to refuel.
Using the graph, approximate the Jet's average gas consumption, in gallons per hour, during the sixteen hour flight from Los Angeles, California to Melbourne, Australia. In your final answer, include all of your calculations.
Answers
26375
On the graph, it tells you how much fuel is left after 2 hours of the journey.
If we take 422,000 and subtract 369,250 from it we get 52,750. However, this is how much gas is used in 2 hours, so to find one hour we need to divide by 2, getting us 26,375.
Therefore, the Jet uses 26,375 gallons per hour during the 16 hour trip from Los Angeles, CA to Melbourne, Australia.
Sinah bought some packs of gum. There were 8 sticks of gum in each pack. She gave 12 sticks of gum to manuela. This left sinah with 28 sticks of gum. Which equation can be used to represent this situation where g is the number of packs of gum that sinah bought?
Answers
Answer:
8g = 12 + 28
g = 5 packs
Step-by-step explanation:
Share of the sticks of gum
Manuela = 12 sticks
Sinah = 28 sticks
There are 8 sticks in each pack
g = number of packs of gum that sinah bought?
g × 8 sticks = 12 sticks + 28 sticks
8g = 40
Divide both sides by 8
g = 40 / 8
g = 5 packs
