Answer 1

-3

Explanation:

Easy way:

Between the two marked points, you can count that you need to go down 6 and over 2. That means the rise/run is -6/2, or -3.

Full way:

Starting Point: (-1,3)

Ending Point: (1,-3)

Slope is given by (y₂-y₁)/(x₂-x₁)

To calculate this, (-3-(3))/(1-(-1))

Clean up the double negatives to get (-3-3)/(1+1), AKA -6/2

-6/2 = -3.
