The unit rate is the rate of change per day or the slope.


To get the slope of the line, we use the slope formula:

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Where [tex](x_{1},y_{1})[/tex] is point 1 on the line and tex](x_{2},y_{2})[/tex] is point 2 on the line.

Let's take 2 points from the line and calculate the slope. We will take the points (0,0) and (1,3) (any two points on the line will give the correct answer).

[tex]m=\frac{3-0}{1-0} \\m=\frac{3}{1}\\m=3[/tex]

This means Barton reads 3 chapters per day. Answer choice C is right.
