| Determine which of the points A (3; -2), B (-2; 4), C (1; 2) and D (-3; 1) belong to the graph of the function.

1) y = -2 * x + 4;

-2 = -2 * 3 + 4;

-2 = -6 + 4;

-2 = -2;

Right;

2) y = -2 * x + 4;

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

4 = 4 + 4;

4 = 8;

Wrong;

3) y = -2 * x + 4;

2 = -2 * 1 + 4;

2 = -2 + 4;

2 = 4 – 2;

2 = 2;

Right;

4) y = -2 * x + 4;

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

1 = 6 + 4;

1 = 10;

Wrong;

Answer: A (3; -2), C (1; 2).
