(0, 3)

Two of these

(2, 5)

(8, 5)

1 answer

To determine which points are on the line defined by the equation \( y = -x + 3 \), we can substitute the x-coordinates of each point into the equation and see if the corresponding y-coordinates match.

  1. For the point \( (0, 3) \): \[ y = -0 + 3 = 3 \] Since the calculated y-value (3) matches the point's y-coordinate (3), this point is on the line.

  2. For the point \( (2, 5) \): \[ y = -2 + 3 = 1 \] Since the calculated y-value (1) does not match the point's y-coordinate (5), this point is not on the line.

  3. For the point \( (8, 5) \): \[ y = -8 + 3 = -5 \] Since the calculated y-value (-5) does not match the point's y-coordinate (5), this point is not on the line.

Based on this analysis, the only point that lies on the line \( y = -x + 3 \) is \( (0, 3) \).

The answer is: (0, 3).
