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

Explanation:

Step 1: Define

Find points from graph.

Point (3, 0)

Point (1, -3)

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=(-3-0)/(1-3)
  2. [Fraction] Subtract:
    \displaystyle m=(-3)/(-2)
  3. [Fraction] Simplify:
    \displaystyle m=(3)/(2)
