Question

What is the slope of the line that passes through the points (2, 9) and (18, -3)?

Write your answer in simplest form.

Answer 1

m =
`(-3)/(4)`

Explanation:

Slope = rise/run or (y2 - y1) / (x2 - x1)

Points (2, 9) and (18, -3)

We see the y decrease by 12 and the x increase by 16, so the slope is

m =
`(-12)/(16)` =
`(-3)/(4)`
