Answer:
<h2> There is no slope.</h2>
Step-by-step explanation:

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, <u>so there is no slope.</u>
{the line is parallel to Y-axis, and has an equation: x=-4}
The measurement should be 130 according to my calculations
