The scatter plot shows the relationship between hours spent

The scatter plot shows the relationship between hours spent studying and the score on final examination The y-intercept of the estimated line of best fir is at (0,b) Enter the approximate value of b in the first response box Enter the approximate slope of the estimated line of best fit in the second response box

Solution

From the figure it can be observed that the line cuts the y-axis at y = 50 approx.

Hence b = 50

Also it can be observed that another point on the line is (2,60)

Hence we have two points on the line that is (0,50) and (2,60)

The slope of the line, then = (60 - 50)/(2-0) = 10/2 = 5 .....................Ans.
