  • Left to Right

Algebra I

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

Explanation:

Step 1: Define

Point (2, 5)

Point (-3, 7)

Step 2: Identify

x₁ = 2, y₁ = 5

x₂ = -3, y₂ = 7

Step 3: 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=(7-5)/(-3-2)
  2. [Slope] [Fraction] Subtract:
    \displaystyle m=(2)/(-5)
  3. [Slope] [Fraction] Rewrite:
    \displaystyle m=(-2)/(5)
