To find which point is a solution to the equation \( y = 2x - 5 \), we need to substitute the x-coordinates of each point into the equation and see if the corresponding y-coordinate matches.

  1. For the point \( (4, 2) \): \[ y = 2(4) - 5 = 8 - 5 = 3 \quad (\text{not a solution}) \]

  2. For the point \( (1, -3) \): \[ y = 2(1) - 5 = 2 - 5 = -3 \quad (\text{is a solution}) \]

  3. For the point \( (-1, -5) \): \[ y = 2(-1) - 5 = -2 - 5 = -7 \quad (\text{not a solution}) \]

  4. For the point \( (2, 0) \): \[ y = 2(2) - 5 = 4 - 5 = -1 \quad (\text{not a solution}) \]

The only point that satisfies the equation \( y = 2x - 5 \) is \( (1, -3) \).
