How do you solve Scatter Plots ? I'm so lost. Help!

Question

Once you have sketched your line, pick two points on your line and determine the coordinates of the two points, $$(x_1,y_1)$$ and $$(x_2,y)$$ . If your sketched line passes through one or two of the scatter plot points, that makes it easy. Otherwise, you will just have to eye-ball it.
