Question

What is the slope of the line through (2,-8) and (4,1)

Answer 1

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

`m=(y_2-y_1)/(x_2-x_1)` And substitute/plug in the two points on the line

(2, -8) = (x₁, y₁)

(4, 1) = (x₂, y₂)

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

`m=(1-(-8))/(4-2)` (two negative signs cancel each other out and become positive)

`m=(1+8)/(4-2)`

`m=(9)/(2)`

Answer 2

9/2. turn each coordinate pair into y/x and subtract them. hope this helps :)
