Here,
y is the dependent variable that is score of exam 3.
x is the independent variable that is the score of exam 1.
Comparing the given equation to a linear equation, we have,
Slope, m = 0.4845
Intercept, c = 50.57
We define the slope as rate of change.
If there is a increase in x by 1 unit, then,
Thus, we can interpret the slope of the line as
