Answer

Answer Choice $H$

Work Step by Step

Find the slope. Choose any 2 points $(x_1,y_1)$, $(x_2,y_2)$ and find the slope by using the formula $m=(y_2-y_1)/(x_2-x_1)$ $m=(9-7)/(35-25)$ $m=2/10$ $m=1/5$ $m = 0.2$ We found the slope. The only answer choice with the slope as $0.2$ is $H$. Another way to do this if you don't understand slope is to trial and error all of the answer choices. Either way, you will get answer choice $H$
