Multiplication
Division
Addition
Subtraction

Left to Right

Algebra I

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (3, 0)

Point (0, 1)

Step 2: Find slope m

Plug in points to find the rate of change of the graph.

Substitute [SF]: $m=\frac{1-0}{0-3}$
Subtract: $m=\frac{1}{-3}$
Rewrite: $m=\frac{-1}{3}$
