Question

Point A is at (3,-4) and point M is at (5.5,0)
Point M is the Midpoint of point A and point B.
What are the coordinates of point B?

Answer 1

Answer:

B(8, 4)

Step-by-step explanation:

Coordinates of a midpoint of a segment with endpoints at A( $x_{1}$ , $y_{1}$ ) and B( $x_{2}$ , $y_{2}$ ) are ( $\frac{x_{1} +x_{2} }{2}$ , $\frac{y_{1} +y_{2} }{2}$ )

~~~~~~~~~~~~~~~~

If M(5.5, 0) is the midpoint of a segment with endpoints at A(3, - 4) and B(x, y), then

(3 + x) / 2 = 5.5 ⇔ 3 + x = 11 ⇒ x = 8      

- 4 + y = 0 ⇒ y = 4    

B(8, 4)
