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. I
s she correct? Explain using complete sentences.
1 answer:
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
the two points from the graph are
(4,40) and (7,70)
substitute the values in the formula
therefore
Catherine is not correct
