Question

What is the slope of the line that passes through the points (-4, 0) and (-4, -10)? Write your answer in simplest form.

Answer 1

There is no slope.

Explanation:

`slope=(y_2-y_1)/(x_2-x_1)`

It means that for a line passing through two points to have the slope, the x-coordinates of these point have to be different.

(-4, 0) and (-4, -10) means x₁ = x₂ = -4, so there is no slope.

{the line is parallel to Y-axis, and has an equation: x=-4}
