Question

What is the slope between (-6,7) and (-6,-3)

Answer 1

There is no slope.

Explanation:

`\bold{slope\, (m)=(change\ in\ Y)/(change\ in\ X)=(y_2-y_1)/(x_2-x_1)}`

(-6, 7) ⇒ x₁ = -6, y₁ = 7

(-6, -3) ⇒ x₂ = -6, y₂ = -3

x₁ = x₂ = -6 means there in no slope;

the line is parralel to Y-axis, and its equation is x = -6
