The slope, mm, is -1/3−13.

Explanation:

The equation to find slope from two points on a line is m=(y_2-y_1)/(x_2-x_1)m=y2−y1x2−x1, where (x_1,y_1)(x1,y1) is one point and (x_2,y_2)(x2,y2) is the other point.

Let (5,-8)(5,−8) be Point 1.
Let (-7,-4)(−7,−4) be Point 2.

Substitute the given values into the equation.

m=(y_2-y_1)/(x_2-x_1)m=y2−y1x2−x1

m=(-4-(-8))/(-7-5)m=−4−(−8)−7−5

Simplify.

m=(-4+8)/(-12)m=−4+8−12

Simplify.

m=4/(-12)m=4−12

Simplify.

m=-4/12m=−412

Simplify.

m=-1/3m=−13
