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

Explanation:

Step 1: Define

Point (-4, -1)

Point (1, 4)

Step 2: Find slope m

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

1. Substitute [SF]:
   `\displaystyle m=(4+1)/(1+4)`
2. Add:
   `\displaystyle m=(5)/(5)`
3. Divide:
   `\displaystyle m=1`
