The midpoint of the coordinates is found by taking the average of the x-coordinates and the average of the y-coordinates.
For the x-coordinate, we have $\frac{0 + (-4)}{2} = -2$.
For the y-coordinate, we have $\frac{7 + (-1)}{2} = 3$.
Therefore, Mark and Sandy will meet at the point $(-2, 3)$.
The answer is: (-2,3)
Below is a math problem. Provide a detailed, step-by-step solution.
