A line segment has (x1, y1) as one endpoint and (xm, ym) as its midpoint. Find the other endpoint (x2, y2) of the line segment i

n terms of x1, y1, xm, and ym. Use the result to find the coordinates of the endpoint (x2, y2) of each line segment with the given endpoint (x1, y1) and endpoint (xm, ym).
(a)

(x1, y1) = (1, −4), (xm, ym) = (2, −1)

(x2, y2)=


(b)

(x1, y1) = (−9, 19), (xm, ym) = (5, 6)

(x2, y2)=

Answer: (a) (x_{2},y_{2}) = (3,2)

              (b)  (x_{2},y_{2}) = (19,-7)

Step-by-step explanation: Midpoint of a segment is halfway between 2 endpoints. It is calculated using the formulas:

x_{m}=\frac{x_{1}+x_{2}}{2}

y_{m}=\frac{y_{1}+y_{2}}{2}

Isolating x_{2}:

2x_{m}=x_{1}+x_{2}

x_{2}=2x_{m}-x_{1}

And y_{2}:

2y_{m}=y_{1}+y_{2}

y_{2}=2y_{m}-y_{1}

(a) Replacing values and calculating x_{2}:

x_{2}=(2*2)-1

x_{2}=3

Calculating y_{2}:

y_{2}=[2*(-1)]-(-4)

y_{2}=2

(x_{2},y_{2})=(3,2)

(b) x_{2}=(2*5)-(-9)

x_{2}=19

y_{2}=(2*6)-19

y_{2} = -7

(x_{2},y_{2})=(19,-7)
