Answer: y = x
Step-by-step explanation: Since the input for the first equation is 2, the x is 2. Use this for the other equation. Now, your ordered pairs are (2,2) and (1,1). If you find Δy/Δx, you get m = 1. Plug in m to the equation. Next, put any ordered pair in there. For example: 1 = 1(1) + b. If you solve for be the answer is..... 0. Nice. Your final equation is y = 1x + 0, or y = x.
