Answer:

Explanation:

To determine which of the given points work for the equation y = 2x - 1, we need to substitute the x and y values of each point into the equation and check if the equation is true.

Let's start with the point (2, 3):

y = 2x - 1

3 = 2(2) - 1

3 = 4 - 1

3 = 3

The equation is true for the point (2, 3).

Now, let's try the point (5, 11):

y = 2x - 1

11 = 2(5) - 1

11 = 10 + 1

11 = 11

The equation is true for the point (5, 11) as well.

Finally, let's try the point (-1, 3):

y = 2x - 1

3 = 2(-1) - 1

3 = -2 - 1

3 = -3

The equation is not true for the point (-1, 3).

Therefore, the points (2, 3) and (5, 11) work for the equation y = 2x - 1, but the point (-1, 3) does not work.
