Answer: 0.624
=====================================================
Explanation:
The regression equation is in the form y = mx+b
- m = slope = -0.624
- b = y intercept = 66.022
The slope tells us how much the value of y changes each time x goes up by 1. In this case, the scores decrease by 0.624 percentage points each time x goes up by 1
You can think of it like saying
- slope = rise/run = -0.624/1
- rise = -0.624 = y drops by 0.624
- run = 1 = x increases by 1
This is why the answer is 0.624. We don't type the negative sign because that is part of the term "decrease".
