Question

Mike is cycling from the library to his home. The equation shows Mike's distance (y), in miles, from his home after x minutes: y = 12 − 2x What does the number 12 in the equation represent?

Answer 1

C, Mikes distance from home when he begins cycling

hope this helps :)

Explanation:

Answer 2

"12" represents Mike's original distance from his home.  As he rides, this distance decreases by 2 miles/minute  (which is rather unlikely, as that'd be 120 mph).
