Question

The values on the x-axis range from negative 10 to 10 in increments of 1. The values on the y-axis range from negative 5 to 15 in increments of 1. The line passes through the following: left parenthesis negative 5 comma negative 3 right parenthesis, left parenthesis negative 4 comma 0 right parenthesis, left parenthesis 0 comma 12 right parenthesis, and left parenthesis 1 comma 15 right parenthesis.

Identify the slope.

Answer 1

Slope m = (0 - (-3))/(-4 - (-5)) = 3/1 = 3.
(You can check with other points: (15-12)/(1-0)=3/1=3.)
