Rey the Beetle crawls at a rate of 4 inches per minute, as modeled by the equation y=4x. His rate decreases by -6 inches per minute. Plot two ordered pairs showing the distances he will crawl at 4 minutes and 5 minutes, respectively, at his new rate.

What is the perimeter, p, of a rectangle that has a length of x + 8 and a width of y − 1? p = 2x + 2y + 18 p = 2x + 2y + 14 p = x + y − 9 p = x + y + 7
