1. Which equation is not an example of a direct variation? A. y = -7/3x+ 1 B. y=5/16x C. y = 4x D. y= -9x

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
