• Slope Formula:
  `m=(y_2-y_1)/(x_2-x_1)`

Explanation:

Step 1: Define

Point (7, -5)

Point (-1, -3)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m.

1. Substitute [SF]:
   `m=(-3+5)/(-1-7)`
2. Add/Subtract:
   `m=(2)/(-8)`
3. Simplify:
   `m=(-1)/(4)`
