Question

Catherine used the two points and the right triangle shown to find the slope of the line. Catherine found the slope to be 1/10. Is she correct? Explain using complete sentences.

Answer 1

Answer:

Catherine is not correct (see the explanation)

Step-by-step explanation:

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

(4,40) and (7,70)

substitute the values in the formula

$m=\frac{70-40}{7-4}$

$m=\frac{30}{3}$

$m=10$

therefore

Catherine is not correct
