Answer:

        There is no slope.

Step-by-step explanation:

[tex]slope=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

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}
