Question

As the x-values increase by 1, the y-values increase by 15. Which equation shows this?

A. y = 15 + x
B. y = 15 - x
C. y = 15x​

Answer 1

Answer:

A. y = 15x

Step-by-step explanation:

To solve this problem, we just need to find the slope, because we are not told about the y-intercept. We can use the slope formula (m = change in y/change in x) to find the answer. Since we are already given the change in y (15) and change in x (1), we just need to substitute the values into the slope formula.

m = 15/1 = 15

This means that our slope is 15, so we can substitute it into the slope-intercept formula to get y = 15x.

Hope this helps!
