  • Slope Formula: [tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Step-by-step explanation:

Step 1: Define

Point (2, 5)

Point (-1, 8)

Step 2: Find slope m

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

  1. Substitute [SF]:                    [tex]\displaystyle m=\frac{8-5}{-1-2}[/tex]
  2. [Frac] Subtract:                    [tex]\displaystyle m=\frac{3}{-3}[/tex]
  3. [Frac] Divide:                       [tex]\displaystyle m=-1[/tex]
