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

To check which points belong to the graph, you need to substitute the coordinates of the points in the equation. If there is equality, then the point fits.

1.A (3; -2);

-2 = -2 * 3 + 4;

-2 = -6 + 4;

-2 = -2.

Point A belongs to the graph.

2. B (-2; 4);

4 = -2 * (-2) + 4;

4 = 4 + 4;

4 = 8.

Point B does not belong to the graph.

3.C (1; 2);

2 = -2 * 1 + 4;

2 = -2 + 4;

2 = 2.

Point C belongs to the graph.

4. D (-3; 1);

1 = -2 * (-3) + 4;

1 = 6 + 4;

1 = 10;

Point D does not belong to the graph.

Answer: points A and C belong to the chart.
