Question

Find the slope of the line that passes through each pair of points.

Answer 1

slope = -
`(1)/(2)`

Explanation:

Calculate the slope m using the slope formula

m =
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`

with (x₁, y₁ ) = (- 4, 7 ) and (x₂, y₂ ) = (8, 1 )

m =
`(1-7)/(8-(-4))` =
`(-6)/(8+4)` =
`(-6)/(12)` = -
`(1)/(2)`
