What is the slope of the line that passes through the points (-8, -4)(−8,−4) and (4, -4) ?(4,−4)? is my answer 3?

The answer to your question is slope = 0

Step-by-step explanation:

Data

Point 1 = (-8, -4)

Point 2 = (4, -4)

Process

1.- Write the formula to calculate the slope

slope = m = (y2 - y1) / (x2 - x1)

2.- Identify x1, y1, x2 and y2

x1 = -8  y1 = -4   x2 = 4  y2 = -4

3.- Substitution

             m = (-4 + 4) / (4 + 8)

4.- Simplification

             m  = 0 / 12

5.- Result

             m = 0
