The given plot is a scatter plot. A linear relationship can be determined from the plot. We can apply the slope intercept equation to determine the linear relationship. It is expressed as

y = mx + c

Where

m represents the slope

c represents the y intercept

y represents the scores

x represents the amount of time spent

We would try to pick points that could possibly form a straight line.

recall:

slope, m = (y2 - y1)/(x2 - x1)

Looking at possible linear points,

x1 = 0.75

y1 = 50

x2 = 2.5

y2 = 70

m = (70 - 50)/(2.5 - 0.75) = 20/1.75

m = 11.4
