Expert Solution
Step 1

Answers may vary based on the points chosen. One of the possible answers is mentioned below.

(c)

The two points chosen from the line of best fit is (45, 87) and (50, 90). Let x1, y1=45,87 and x2, y2=50, 90. The slope from these two points is,

Slopem=y2-y1x2-x1=90-8750-45=35=0.6

Thus, the slope of two points is 0.6.

The line using the point slope formula is,

y-y1=mx-x1y-87=0.6x-45y=87+0.6x-27y=0.6x+60

Thus, the equation of line in slope-intercept form is y=0.6x+60.
