Question

what is an equation of the line that has slope -4 and passes through the point (-2,-5)
A. y= -4x-8
B. y= -4x-13
c. y=-4x-5
D. y=-4x+3

Answer 1

y = mx + b
m = -4
(-2,-5) x = -2 and y = -5
now we sub
y = mx + b
-5 = -4(-2) + b
-5 = 8 + b
-5 - 8 = b
- 13 = b

your equation is : y = -4x - 13

Answer 2
