Points that lie on the line with the equation given must correctly fill in the equation. For example, answer (1,8) gives an X value of 1, from which we can calculate y = 3(1) +5 = 8. Thus, the point (1, 8) must lie on the line. Answer (3,16) does not lie on the line, because if we enter an X value of 3, then y = 3(3) + 5 = 14, which does not match with the point’s value of (3,16). Thus, Answer (3,16) does not lie on the line.
