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

Cut each sandwich into pieces of thirds
4 sandwiches x 3 pieces = 12 total pieces
--------------------
12 / 6 = 2
Everybody would get 2 pieces
