Question

Find the slope of the line passing through the given points

Answer 1

slope = 2

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 ) = (2, 2) ← 2 points on the line

m =
`(2-(-4))/(2-(-1))` =
`(2+4)/(2+1)` =
`(6)/(3)` = 2
