Question

]What is the x-coordinate of the midpoint of AB given A(-10,0) and B(-5,9).

Answer 1

The x-coordinate of the midpoint of AB is -7.5.

Step-by-step explanation:

To find the x-coordinate of the midpoint of AB, we first need to find the coordinates of both points A and B. From the given information, we have A(-10,0) and B(-5,9). Next, we calculate the average of the x-coordinates of A and B to find the x-coordinate of the midpoint. The average is (-10+(-5))/2 = -15/2 = -7.5. Therefore, the x-coordinate of the midpoint of AB is -7.5.
