Question

What the slope of the line

Answer 1

slope = -
`(8)/(5)`

Explanation:

calculate the slope m using the slope- formula

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

with (x₁, y₁ ) = (- 1, 4) and (x₂, y₂ ) = (4, - 4) ← 2 points on the line

m =
`(-4-4)/(4-(-1))` =
`(-8)/(4+1)` =
`(-8)/(5)` = -
`(8)/(5)`
