Explanation / Answer

a) Since the number of work hours increase and the slope of work is -ve, this means that as the work hours increase, the credits decrease. Hence, option A is correct

b) If we put work=0, the credits are still 14.9 .Option B is correct

c) If work is 0 credits are 14.9

Putting work=30, the credits are 14.9-0.09*30=12.2
