Left to Right

Algebra I

Coordinates (x, y)
Slope Formula: $\displaystyle m = \frac{y_2-y_1}{x_2-x_1}$
Perpendicular lines are the negative reciprocal of the given line

Step-by-step explanation:

Step 1: Define

Identify

Point G(-2, 3)

Point H(1, -2)

Step 2: Find slope m

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

Line GH

Substitute in points [Slope Formula]: $\displaystyle m = \frac{-2-3}{1--2}$
[Fraction] Subtract: $\displaystyle m = \frac{-5}{3}$

Perpendicular line

Negative: $\displaystyle m = \frac{5}{3}$
Reciprocate: $\displaystyle m = \frac{3}{5}$
