Slope
• slope—ratio of the rise to the run of a line

m = variable that stands for slope

Negative Fractions

Why are these fractions equal?

Find Slope
• First way to find slope is to look at the graph

b)

a)

Ex 1: Find the slope

Horizontal line—slope of 0

d)

c)

Ex 1: Find the slope

Vertical line—slope of undefined

Determine rate of change
• A car travels 50 miles in 2 hours and 175 miles in 5 hours. Determine the cars rate of change.
