y = -13/2

-3x - 13/2 = 8/2

-3x = 21/2

-6x = 21

x = -21/6 = -7/2

A line contains the points (0,-3) and (-8,-9)which of the following represents the equation of the line?
Amanda [17]

Answer: C. y = 0.75x - 3

Step-by-step explanation:

y = mx + b

m = slope

b = y-intercept

Slope = -9 - (- 3) /  -8 - 0 = -9 + 3/ -8 - 0 = -6/-8 = 0.75

Y-intercept = -3

y = 0.75x + (- 3)

y = 0.75x - 3

Hope that helped!
