Question

What is the slope of the line that goes through points (-1,8) and (3,-4)?

Answer 1

Below

Explanation:

Slope , m is defined as (y1-y2)/(x1-x2)

it does not matter which point you call one and which you call two ...

m = ( 8 - - 4) / (-1 -3) = 12/ (-4) = - 3 slope

Answer 2

`slope=(y2-y1)/(x2-x1)`

Label the coordinates:

(-1, 8) (3, -4)

point 1 point 2

`slope=(-4-8)/(3-(-1))`

`slope=(-12)/(4)`

`\fbox{slope = -3}`
