With even just two points, you can find the equation of a line in slope-intercept form.
Slope-intercept form: [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept
1) Solve for the slope ([tex]m[/tex])
The equation to solve for the slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] when the two points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. Plug the coordinates of these points into the equation and solve for [tex]m[/tex].
Then, plug [tex]m[/tex] into [tex]y=mx+b[/tex].
1) Solve for the y-intercept ([tex]b[/tex])
Then, take any of the given points and plug it into [tex]y=mx+b[/tex] along with the slope. Isolate [tex]b[/tex] to get the y-intercept. Then, plug both m and b back into [tex]y=mx+b[/tex] to get your final equation.

If triangle ABC is similar to triangle PQR, find the value of x and y.
Answer:
x = 9
y = 6
Step-by-step explanation:
ΔABC ~ ΔPQR
Therefore, corresponding sides of these similar triangles will be in the proportional.
[tex]\frac{AB}{PQ}=\frac{BC}{QR}= \frac{AC}{PR}[/tex]
[tex]\frac{6}{x}= \frac{4}{y}= \frac{8}{12}[/tex]
[tex]\frac{6}{x}= \frac{8}{12}[/tex]
x = [tex]\frac{12\times 6}{8}[/tex]
x = 9
Similarly, [tex]\frac{4}{y}= \frac{8}{12}[/tex]
y = [tex]\frac{12\times 4}{8}[/tex]
y = 6
The graph shows the relationship between the distance a car is driven and the number of gallons of gasoline used. Identify the value in d in the point (1, d). What does that point represent?
A. d=25; the unit rate is 25 miles per gallon
B. d=25; the unit rate is 25 gallons per mile
C. d=50; the unit rate is 50 miles per gallon
D. d=50; the unit rate is 50 gallons per mile
Answer:
A. d = 25; the unit rate is 25 miles per gallon
Step-by-step explanation:
The point (1, d) on the graph represents (x, y), where,
x = gasoline used = 1 gallon
y = distance = d = 25 miles
That is, (1, d) represents when x = 1, y = 25.
Thus, (1, 25) is the unit rate which is 25miles per gallon.
60 is 25% of what number is
Answer:
240
Step-by-step explanation:
60 = x * 0.25 ----Divide each side by 0.25
60/0.25 = x
240 = x
Answer:
240
Step-by-step explanation:
25% is a fourth of 100%
So if 60 is 25% of something, you would multiply it by 4
60*4=240

[tex]y=3\frac{3}{5}[/tex]
Answer: The answer would be 3.6
You first want to add 4 to both sides to get y on one side by itself. So it would look something like this: -2/5+4=y. Then you can add which gives you y=3.6

Find:
5% of 90 m =
m
25% of 88 kg =
kg
75% of 264 =
Answer:
1) 5% of 90m= 4.5m
2)25% of 88kg = 22kg
3) 75% of 264= 198
Step-by-step explanation:
1) 90m = 100% (divide by 10)
9 = 10% (divide by 2)
4.5 = 5%
2) 88kg = 100% (keep on dividing by 2)
44kg = 50%
22kg=25%
3) 264 = 100%
132 = 50%
66 = 25% (add)
198=75%
which of the following are magnitudes for rotational symmetry of the rectangle below about the marked point?
Answer:
The answer is B.180°.
Step-by-step explanation:
The figure is rotationally symmetric is after a rotation of a given angle, it still look the same.
In this case of a rectangle, the only way to rotate it so that is look the same, is by rotating it by multiple of 180°, so that the up and down sides flip over, as well as the right and left sides.
Therefore, the only option that applies is B.180°
Answer:
B
Step-by-step explanation:
What side length did Mr.Freeman measure the second time?
Answer: D) 2.33 meters
==========================================================
Explanation:
The hundredths digit is 1/10 of the tenths digit. Because of this, the tenths and hundredths digit must be the same digit.
Only choice D fits the description.
The digit in the tenths place represents the value 0.3
Taking 1/10th of this leads to (1/10)*0.3 = 0.1*0.3 = 0.03
So the hundredths place represents the value 0.03
Note that,
2 + 0.3 + 0.03 = 2.33 meters

Which expressions are equivalent to 6.6.6.6.6? Choose 2 answers
Answer:b and c
Step-by-step explanation:
Your restaurant bill comes to $46.27. Estimate a 10% tip.
If the bill of the restaurant comes to $46.27 then the tip of 10% is equal to $4.627.
What is percentage?Percentage is number or ratio that is expressed as a fraction of 100. It is shown by % sign. It shows some quantity over other quantity. The number which shows the percentage is the number in the quantity itself.
How to calculate percentage?We have been given that the bill of the restaurant comes to $46.27 and 10% is the tip. We have to calculate the tip.
Tip=Bill*10/100
=46.27*10/100
=4627*10/100*100
=46270/10000
=$4.627
Hence if the bill of the restaurant is $46.27 then tip will be $4.627.

The answer is B) 75
Step-by-step explanation:
The angle shown is a 90-degree angle. Therefore if the other angle is 15 degrees, that means that all we have to do is subtract 15 from 90.
90-15= 75 which means the angle known as x is a 75-degree angle.
