  • Coordinates (x, y)
  • Slope Formula: [tex]\displaystyle m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Step-by-step explanation:

Step 1: Define

Identify

Point (1, 3)

Point (10, 25)

Step 2: Find slope m

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

  1. Substitute in points [Slope Formula]:                                                              [tex]\displaystyle m = \frac{25 - 3}{10 - 1}[/tex]
  2. Subtract:                                                                                                             [tex]\displaystyle m = \frac{22}{9}[/tex]
