To find the y-value for a house with a size of 1,800 square feet using the line of best fit, we substitute x=1800 into the equation y = 142.2x - 11,156.
y = 142.2(1800) - 11,156
y = 256,560 - 11,156
y = $245,404
Therefore, the cost of a house with a size of 1,800 square feet is $245,404 according to the line of best fit.
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 $s50,000, what is the y value given the line of best fit?
