Question

The points in the table lie on a line. What is the slope of the line?

Answer 1

To find the slope(m), use the slope formula:

`m=(y_2-y_1)/(x_2-x_1)` And plug in two points on the line. I will use

(-2, 1) = (x₁, y₁)

(4, -6) = (x₂, y₂)

`m=(y_2-y_1)/(x_2-x_1)`

`m=(4-(-2))/(-6-1)` (two negative signs cancel each other out and become positive)

`m=(4+2)/(-6-1)`

`m=(6)/(-7)`
