Question

Vhich point-slope equation represents a line that passes through (3,-2) with a slope of -4/5 ?

Answer 1

y = -4/5x + 2/5

Explanation:

Slope form of an equation is y = mx + b

Sub in x and y coordinates and slope then isolate for b

-2 = -4/5(3) + b

-2 = -12/5 + b

-2 + 12/5 = b

b = -10/5 + 12/5

b = 2/5

Sub in b and the slope into the slope form equation

y = (-4/5)x + 2/5
