What is the slope of (-7,5) and (5,-1)

-1/2

Step-by-step explanation:

Method 1)

Use the graph

You must go from point (-7, 5) to point (5, -1) by using only vertical and horizontal paths.

Start at point (-7, 5).

Go down 6 units. That means a rise of -6.

Now go right 12 units to point (5, 1)

That is a run of 12 units.

slope = rise/run = -6/12 = -1/2

Method 2)

Use the slope formula

slope = (y2 - y1)/(x2 - x1) = [5 - (1)]/(-7 - 5) = (5 + 1)/(-12) = 6/(-12) = -1/2
