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

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]:
   `\displaystyle m = (25 - 3)/(10 - 1)`
2. Subtract:
   `\displaystyle m = (22)/(9)`
