Khan academy midpoint formula question!! Please help

Answer 1

3,-7 is the answer for this question

Answer 2

Answer:

The answer to your question is B = B (3, -7)

Step-by-step explanation:

Data

A = (-6, 5)

M = (-1.5, -1)

Process

1.- Write the formula of Midpoint

Xm = (x1 + x2)/2

Ym = (y1 + y2)/2

2.- Solve for x2 and y2

x2 = 2Xm - x1

y2 = 2Ym - y1

x1 = -6   y1 = 5   Xm = -1.5  Ym = -1

3.- Substitution

x2 = 2(-1.5) + 6

y2 = 2(-1) - 5

4.- Simplification

x2 = -3 + 6

y2 = -2 - 5

5.- Result

x2 = 3

y2 = -7

B (3, -7)
