Finding the slope of a line… Unit 5

YIP : Slope is the steepness of a line. 7% So, what is slope??? YIP : Slope is the steepness of a line.

Today we are going to find the slope of linear function. YIP: Linear

YIP: slope = rise run

Slope can be expressed different ways:

YIP Slopes: positive, negative, no slope (zero), undefined.
