Question

Calculator Reference Jeremy has a weekend job as a soccer referee. One weekend, he earns $140 by working 4 games. Another weekend, he earns $210 by working 6 games. If Jeremy graphed an equation that would represent his total earnings based on the number of games worked, what would be the slope of the graph?

Answer 1

The slope of your graph would be 35

(or if you were to put this in an equation it would be 35x)

Still confused? I'll explain the first answer:

If you were to put Jeremy's two earnings on a graph, you would have to convert them to points.

In this case, your points would be (4, 140) and (6, 210), then you would use the formula to convert the points into a slope:

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Then, plug those numbers in:

$\frac{210-140}{6-4}$

And after, reduce:

$\frac{70}{2} =35$
