It is y=2x+2. The slope is 2 and the y intercept is 2
11.25×12.5 = 140.625.
Depending on your class, you may only need 140 or round to 141.
I think that since their is no = sign you can’t have just one nimber because you can’t fully simplify... I got 4c-12
divide 13 by 3
13/3 = 4.33 put a bar over the 2nd 3 because it just keeps repeating.
