Consider the following equations:
y = x minus 2. y = 2 x minus 2. y = negative x minus 2. y = negative 2.
Discuss the similarities and difference in the graphs of these equations. (Use a graphing calculator if needed.)
a.
Same slopes; different y-intercepts
b.
Same slopes; same y-intercepts
c.
Different slopes; same y-intercepts
d.
Different slopes; different y-intercepts
Please select the best answer from the choices provided
A
B
C
D
plz help i'm begging you i don't want to fail this plz help
Answer:
C
Step-by-step explanation:
Different slopes; same y-intercept
Use a graphing calculator or an online one, like desmos to help visualize
y=x minus 2
y=2x minus 2
y= negative X minus 2
y=negative 2
If you were to type this on a graphing calculator
*Notice how all of these functions intersect at the same point on the y axis . That is because they all share the same y-intercept of -2
* The slopes are all different using the rise over run method.
Slope of y=x minus 2 is 2/2 or 1
Slope of y=2x minus 2is 2/1 or 2
Slope of y=negative X minus 2 is 2/-2 or -1
Slope of y= negative 2 is 0
Match the terms to their definition.
1. part-whole ratio
a ratio comparing a portion of a whole quantity to the whole quantity
2. ratio
a comparison of two quantities or numbers as a quotient
3. part-part ratio
a ratio comparing two portions of a whole quantity to each other
This graph shows a proportional relationship, y=kx. What is the constant of proportionality, k?
The constant of proportionality, k is equal to 7.
What is proportionality?The term proportionality describes any relationship that is always in the same ratio.
Given that, a graph shows a proportional relationship y = kx, is in the form of equation of a line, y = mx + c, where, m is the slope, so we can say that, the k here is the slope.
Slope = y₂-y₁ / x₂-x₁
= 35-21 / 5-3
= 14 / 2
= 7
Since, the slope of the line is 7 therefore, k = 7.
Hence the constant of proportionality, k is equal to 7.

Math: There are 30 pages in a chapter of your textbook. You read 40%, how many pages do you have left to read? Explain how to solve this using 2 different methods
Answer:
18 pages left
Way 1: Find what 40% of 30 is and subtracting it from 30, leaving 60% of 30 left:
40% of 30 is 0.4*30 = 12, 30 - 12 = 18
Way 2: Subtract 40% from 100% and multiply it by 30: 100% - 40% = 1 - 0.4 = .6, 0.6*30 = 18

Answer:3.25 burger, 13.00 souvenir, 19.50 pass.
Step-by-step explanation:
1:4:6 is the ratio “1/4 of the” souvenir aka 1:4. “The souvenir is two thirds” 4 is 2/3 3/3=6 hence 1:4:6
38.75-3 for the actual amount of money spent is 35.75 divided by 11 for one unit is 3.25
so for the burger 1x3.25=3.25. for the souvenir 4x3.25=13. And for the pass 6x3.25=19.5

Answer: 7/10, 7/10 and 3/10.
Step-by-step explanation:
7/10 = Between 1 and 10, the multiples of three are 3, 6, and 9. So the amount favourable outcomes is the total minus the multiples, 10-3 = 7. So 7/10.
7/10 = Between 1 and 10, the multiples of 2 are 2, 4, 6, 8, and 10. The multiples of 3 are 3, 6 and 9. That, gives 7 favourable outcomes (6 is a multiple of both but counted once) giving the probability of 7/10.
3/10 = The favourable outcome is 8 and above, so: 8, 9 and 10. There are 3 favourable outcomes which gives the probability of 3/10.
