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?

Answer 1

To find the y value, we will substitute x = 1,800 into the equation of the line of best fit:

y = 142.2(1,800) - 11,156
y = 255,960 - 11,156
y = $244,804

Therefore, the cost of a 1,800 square feet house according to the line of best fit is $244,804.
