Answer: -3

Step-by-step explanation:

To find the slope of a line we need two coordinates on the line. Any two coordinates will suffice. We are basically measuring the amount of change of the y-coordinate, often known as the rise, divided by the change of the x-coordinate, known the the run. The calculations in finding the slope are simple and involves nothing more than basic subtraction and division.

SashulF [63]

Answer:i think it is y-y1=m(x-x1)

m is herein undefined.

Slope, m, is defined as change-of-y divided by change-of-x...

m=(y-y1)/(x-x1)

The mathematical concept of undefined means that the denominator is zero.  This means that both values of x are equal.

(-4,-8)

This equation is x=-4
