Question

The midpoint of (AB) is M (-5,-3). If the coordinator of A are (-8,-7) is M (-5,-3). If the coordinates of A are (-8,-7), what are the coordinates of B

Answer 1

x-coordinate of M = (x1 + x2) / 2
y-coordinate of M = (y1 + y2) / 2

Given that the coordinates of M are (-5, -3) and the coordinates of A are (-8, -7), we can substitute these values into the formulas to find the coordinates of B:

x-coordinate of B = 2 * x-coordinate of M - x-coordinate of A = 2 * (-5) - (-8) = -10 + 8 = -2
y-coordinate of B = 2 * y-coordinate of M - y-coordinate of A = 2 * (-3) - (-7) = -6 + 7 = 1

Therefore, the coordinates of B are (-2, 1).
