Question

Need Help on Both of these, Will give 50 Points to answerer:

Answer 1

Part A: Scatter plot with best-fit line attached. You'll find the line to have equation (approximately)

$y=51.34+3.98x$

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

$\dfrac{40-30}{4-2}=5$

and assuming the line passes through (2, 30) exactly, it would have equation

$y-2=5(x-30)\implies y=5x-148$
