Part A: Scatter plot with best-fit line attached. You'll find the line to have equation (approximately)
The positive slope suggests that test scores and study time are directly are proportional.
Part B: Same as in a previous question you had posted. Pick two points on the provided line and compute the slope as best you can. For example, I might pick (2, 30) and (4, 40), which gives a slope of
and assuming the line passes through (2, 30) exactly, it would have equation
