Final answer:

To find the coordinates of point B, we used the midpoint formula, given the midpoint M(-4, 0) and point A(-6, 6). After solving two equations, we determined that the coordinates of B are (-2, -6).

Step-by-step explanation:

To determine the coordinates of point B given that M is the midpoint of segment AB with the coordinates of A provided, we use the midpoint formula. The midpoint M is calculated using the formula:


M = ((x1 + x2)/2, (y1 + y2)/2)

Since we are given M(-4, 0) and A(-6, 6), we can set up the equations:

-4 = (-6 + x2)/2

0 = (6 + y2)/2

By solving these two equations, we can find x2 and y2, the coordinates of point B. Multiplying both sides by 2 to clear the fractions, we get:

-8 = -6 + x2 and 0 = 6 + y2

Isolating x2 and y2 gives us the coordinates for B:

x2 = -8 + 6 = -2

y2 = 0 - 6 = -6

So the coordinates of point B are (-2, -6).
