Question

What is the slope of the line passing through(-7, 8) (-8, 8) is?

Answer 1

Answer:

slope = 0

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 7, 8 ) and (x₂, y₂ ) = (- 8, 8 )

m = $\frac{8-8}{-8-(-7)}$ = $\frac{0}{-8+7}$ = $\frac{0}{-1}$ = 0

Answer 2

Answer:

Step-by-step explanation:

(-7, 8) (-8, 8)

(y2 - y1) / (x2 - x1)

(8 - 8) / (-8 + 7)

0 / -1

the slope is 0

you could also see this because the y value doesn't change

if the y value doesn't change the slope is 0, if the x value doesn't change the slope is undefined
