Answer 1

ответ б и в будут правильными.

Answer 2

Points not belonging to the graph of the function y = 2x - 1

To determine which of the given points do not belong to the graph of the function y = 2x - 1, we can substitute the x and y values of each point into the equation and check if the equation holds true.

Let's check each point:

1. Point A (0, -1): - Substituting x = 0 and y = -1 into the equation y = 2x - 1: - -1 = 2(0) - 1 - -1 = -1 - The equation holds true for point A.

2. Point B (4, 7): - Substituting x = 4 and y = 7 into the equation y = 2x - 1: - 7 = 2(4) - 1 - 7 = 8 - 1 - 7 = 7 - The equation holds true for point B.

3. Point C (-1, 1): - Substituting x = -1 and y = 1 into the equation y = 2x - 1: - 1 = 2(-1) - 1 - 1 = -2 - 1 - 1 = -3 - The equation does not hold true for point C.

Therefore, the point (-1, 1) does not belong to the graph of the function y = 2x - 1.

Summary: Out of the given points, only point C (-1, 1) does not belong to the graph of the function y = 2x - 1.
