Janie was given (-2,3) as the endpoint of a line segment and (1,0) as its midpoint. Which ordered pair should Janie choose as the other endpoint?

A(-1/2, 3/2)
B(1/2, 1/2)
C(-5,6)
D(4,-3)

Verified Answer :

\(\frac{-2+x}{2}=1\)∧\(\frac{3+y}{2} =0\)⇔\(x = 4\) ∧\(y = -3\)
R: D (4, -3)

Answer:

The other endpoint

\((x_{2} , y_{2}) is (4,-3)\)

Step-by-step explanation:

Given

Point 1 (-2,3)

Midpoint = (1,0)

We're to calculate the other end point.

To solve this, we'll make use of the formula of midpoints of line

Given that two lines of coordinates \(P(x_{1} ,y_{1} )\) and \(Q(x_{2} ,y_{2} )\)

\((m_{1},m_{2}) = (\frac{(x_{1} + x_{2} )}{2} ,\frac{(y_{1} + y_{2} )}{2})\\Where\\m_{1} = \frac{(x_{1} + x_{2} )}{2} \\and\\m_{2} = \frac{(y_{1} + y_{2} )}{2})\\\)

From the question, we have

\(m_{1} = 1\\m_{2} = 0\\x_{1} = -2\\y_{1} = 3\\\)

Calculating \(x_{2}\)...

From \(m_{1} = \frac{(x_{1} + x_{2} )}{2}\)

By Substitution, we have

\(1 = \frac{-2+x_{2} }{2} \\2 = -2+x_{2}\\2 + 2 = x_{2}\\ x_{2} = 4\)

Calculating \(y_{2}\)...

From \(m_{2} = \frac{(y_{1} + y_{2} )}{2}\)

By Substitution, we have

\(0 = \frac{3+y_{2} }{2} \\0 = 3+y_{2}\\0 - 3 = y_{2}\\ y_{2} = -3\)

Hence, the other endpoint

\((x_{2} , y_{2}) is (4,-3)\)
