The line of best fit is y = 142.2x - 11,156. This line shows the comparison of house size in comparison to the cost of the house. If the size of the house, 1,800 square feet, gives the cost of $250,000, what is the y value given the line of best fit?

Question

A. $244,804
B. $250,000
C. $267,116
D. $2,855,489,760

Answer 1

To find the y value given the line of best fit, you use the equation y = 142.2x - 11,156 and substitute x = 1800 into the equation:

y = 142.2(1800) - 11,156
y = 256,560 - 11,156
y = 245,404

Therefore, the y value given the line of best fit is $245,404.

The closest option to this answer is A. $244,804.
