Answer:

Catherine is not correct (see the explanation)

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

the two points from the graph are

substitute the values in the formula

m=\frac{70-40}{7-4}\\m=\frac{30}{3}\\m=10

therefore
