Point M is the midpoint of AB. If the coordinate of A are (-3,6) and the coordinates of M are (-5,2), what are the coordinates of B?

I bet it is (-7,-2).

all I did was calculate the difference in the x's, and y's, and add them to the Midpoint.

To find the coordinates of point B, we can apply the midpoint formula. The midpoint formula states that the coordinates of the midpoint (M) between two points (A and B) can be found by averaging the x-coordinates and the y-coordinates of the two given points.

Let's first find the difference between the x-coordinates of M and A:
Δx = x coordinate of M - x coordinate of A = -5 - (-3) = -5 + 3 = -2

Now, let's find the difference between the y-coordinates of M and A:
Δy = y coordinate of M - y coordinate of A = 2 - 6 = -4

The differences Δx and Δy represent the changes in the x-coordinate and y-coordinate, respectively, from point A to point B.

To find the coordinates of point B, we can add the differences (Δx and Δy) to the x-coordinate and y-coordinate of point A, respectively:
x coordinate of B = x coordinate of A + Δx = -3 + (-2) = -3 - 2 = -5
y coordinate of B = y coordinate of A + Δy = 6 + (-4) = 6 - 4 = 2

Therefore, the coordinates of point B are (-5, 2).
