I'm assuming this means solve for x in which case:
y=ax+b
y-b=ax
(y-b)/a = x
pi = 3.14...
pi^2 = 9.86...
3^2 = 9
4^4 = 16
Pi is between sqrt(9) and sqrt(16).
They got 5 yards on 3 plays. For total yards multiply the 3 plays by 5 yards. The first play was negative, so add the negative value. The answer is A.
