Question

What is the slope of the line shown in graph below?

Answer 1

slope = 3

Explanation:

calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (- 2, - 5) and (x₂, y₂ ) = (1, 4) ← 2 points on the line

substitute these values into the formula for m

m =
`(4-(-5))/(1-(-2))` =
`(4+5)/(1+2)` =
`(9)/(3)` = 3
