Hi,

The answer to your question is either A or B.

The y-intercept is at point (0,60). All the other options (C and D) do not make sense and just aren't logically.

The y-intercept (0,60) literally shows that if a student studies 0 hours they can expect to score a 60 on the test.

Thus, you're answer is option B.

the answer is B

The Y-intercept would be when x is 0 which in this graph is 60
