Question

Find the slope of the line graphed below.

Answer 1

slope =
`(2)/(5)`

Explanation:

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (- 2, - 1) and (x₂, y₂ ) = (3, 1) ← 2 points on the line

m =
`(1-(-1))/(3-(-2))` =
`(1+1)/(3+2)` =
`(2)/(5)`
