Answer:
c
Step-by-step explanation:
you divide each side by four to get a=2.5 b=2.5 and c=3
There is no one answer (ordered pair) to this equation and the answer is found by graphing or trying out different values for each variable. Anyway, here are some solutions; (1,0), (4,1), (0,-1/3).
The slope is 2, because you subtract the points 3,17 from 7,25 to get 8/4/ Simplify that into 2.
