1. Find the equation in slope-intercept form for the line passing through the points (-1,-5) and (-3,1).

Respuesta :

Answer:

y = - 3x - 8

Explanation:

y = mx + b

where m is the gradient

m = change in y / change in x

m = 1 - ( -5) / -3 - (-1)

m = 1 + 5 / -3 + 1

m = 6 ÷ - 2

m = -3

-3 = y + 5 / x + 1

-3 ( x + 1) = y + 5

-3x - 3 = y + 5

y = -3x -3 -5

y = -3x - 8
