For this case what you should do is use the linear equation that Bryce wrote and replace the corresponding value of y which is 67.5 inches. Then, you must clear x to find the height. We have y = 1.123x-6.443 67.5 = 1.123x-6.443 Clearing x x = (67.5 + 6.443) / (1.123) = 65.84 The best prediction of Riley's height is 65.84 inches. answer B) 65.84 inches
