The equation of the line of best fit for variables x and y is \(y = 19.33 + 0.42x\), where x is the independent variable. Estimate the value of y when x = 15.

Answer Details

The equation given is in the form y = mx + b, where m is the slope and b is the y-intercept of the line of best fit. In this case, the slope is 0.42 and the y-intercept is 19.33. To estimate the value of y when x = 15, we simply substitute x = 15 into the equation and solve for y: y = 19.33 + 0.42(15) y = 19.33 + 6.3 y = 25.63 Therefore, the estimated value of y when x = 15 is 25.63.
