3.4 Two-Variable Data & Models - Line of best fit
0:00
The figure presents a sterplot titled “Ice Cream Sales.” The horizontal axis is labeled “Temperature, in degrees Celsius,” and the integers 10 through 26, in increments of 2, are indied. The vertical axis is labeled “Sales, in dollars,” and the integers 300 through 1,000, in increments of 100, are indied. There are 12 data points in the sterplot, and the line of best fit is drawn. The line of best fit begins slightly above the horizontal axis, and slightly to the right of the vertical axis, and slants upward and to the right. It passes through the point 12 comma 480 and the point 24 comma 880.

The sterplot above shows a company’s ice cream sales d, in dollars, and the high temperature t, in degrees Celsius (°C), on 12 different days. A line of best fit for the data is also shown. Which of the following could be an equation of the line of best fit?

A.

d equals, 0 point 0 3 t plus 402

B.

d equals, 10 t plus 402

C.

d equals, 33 t plus 300

D.

d equals, 33 t plus 84
