# Which of these points A (3: -2), B (-2: 4), C (1: 2), D (-3: 1) belong to the graph of the function y = -2x + 4?

| Since each point has its own coordinates (x: y), then instead of the x in the equation we substitute the “x” coordinate, and instead of the game, the “y” coordinate.

Point A (3: -2):

-2 = -2 * 3 + 4

-2 = -2

So point A belongs to this graph.

Similarly, point B (-2: 4):

4 = -2 * -2 + 4

4 is not equal to 8, so point B does not belong to the graph.

C (1: 2):

2 = -2 * 1 + 4

2 = 2

Point C belongs to the graph.

D (-3: 1):

1 = -2 * -3 + 4

1 is not equal to 10, so point D does not belong to the graph.
