The slope, m, is 8/3.

Explanation:

The equation to find the slope of a line from two points is m=(y_2-y_1)/(x_2-x_1), where m is the slope, (x_1,y_1) is the first point, and (x_2,y_2) is the second point.

First point: (4,7)
Second point: (1,-1)

Substitute the given values into the equation.

m=(y_2-y_1)/(x_2-x_1)

m=(-1-7)/(1-4)

Simplify.

m=(-8)/(-3)

Simplify.

m=8/3

Note: It doesn't matter which point is first or second, as long as you are consistent.
