Question

How do you find the slope of (-4,-8); (-2,0) without a graph?

Answer 1

m = 4

Explanation:

To find slope use the`color(blue)(" gradient formula")`

`m = (y_2- y_1)/(x_2 - x_1)`

where (`x_1 , y_1) ,(x_2 , y_2 )color(black)( " are 2 points ")`

for this question let

`( x_1 , y_1 ) = (- 4 , - 8 ) color(black)(" and ") (x_2 , Y_2) = (-2,0)`

substitute values into formula :

`m =( 0 -(-8))/(-2-(-4)) = 8/2 = 4`
