It would be C because if you make the equation into y=mx+b then it would look like y = -1/2x + 2. The b=2 and the b is the y-intercept. The point (0,2) is on the y-axis and the 2 would be the y-intercept which makes it the b in y=mx+b if the line passes through (0,2). Hope that helps. Also try to do the question and if you got a different answer see what could be a possible mistake. If you try to solve the problem it could improve you skills in math and you would not have to ask for help!
