Which group of points are all on the line y = -2x + 1?

A (3, â€“5); (1, â€“1); (2, â€“3) B(3, â€“7); (1, â€“3); ( 2, â€“3) C (3, â€“7); (1, â€“1); ( 2, â€“5) D(3, â€“5); (1, â€“3); (2, â€“5)

Let's say that choice C was the answer (this is hypothetical for now since we don't know yet) If it was, then (3, â€“7), (1, â€“1), and ( 2, â€“5) would be solutions If (3,-7) was a solution, then x = 3 and y = -7, so... y = -2x + 1 -7 = -2(3) + 1 -7 = -6 + 1 -7 = -5 ... which is false. So (3, â€“7) is NOT a solution, which means choice C is NOT the answer. Do the same with the other answer choices to see if those points are solutions.
