Shark is born measuring 21 inches in length. after 2 months, the shark is now 55 inches long. if x is the age of the shark in months, then y is the length of the shark in inches. at what rate is the shark growing? state your answer as a reduced fraction.  inches per monthfind an equation of a line in the form y = mx + b that describes the shark's length.

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .
