Answer:

The slope is \frac{5}{4}

Step-by-step explanation:

Slope of a dataset:

The slope of a dataset, having two points, is given by the change in y values divided by the change in x values

In this question:

Two points:

x = 0, y = 8

X = 4, y = 13

The slope is:

m = \frac{13 - 8}{4 - 0} = \frac{5}{4}

The slope is \frac{5}{4}
