Final answer:
To find the coordinates of the midpoint of XZ, we need to find the average of the x-coordinates and the average of the y-coordinates of the two points. The coordinates of the midpoint of XZ are (-7, 8.5).
Step-by-step explanation:
To find the coordinates of the midpoint of XZ, we need to find the average of the x-coordinates and the average of the y-coordinates of the two points. The x-coordinate of the midpoint is the average of the x-coordinates of X and Z. (-10 + (-4))/2 = -7. The y-coordinate of the midpoint is the average of the y-coordinates of X and Z. (9 + 8)/2 = 8.5. Therefore, the coordinates of the midpoint of XZ are (-7, 8.5).
