The midpoint of a segment is (6,−4) and one endpoint is (13,−2). Find the coordinates of the other endpoint.

KengaRu [80]

Answer: A. (-1, -6)

Step-by-step explanation:

Use the midpoint formula:

Endpoint #1 = (x₁, y₁) = (13, -2)
Endpoint #2 = (x₂, y₂)

$midpoint = (\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}) \\\\(6, -4) = (\frac{13+x_{2}}{2}, \frac{-2+y_{2}}{2})\\\\\frac{13+x_{2}}{2} =6\\\\13+x_{2}=6*2\\\\x_{2}=12-13=-1\\\\ \\ \frac{-2+y_{2}}{2}=-4\\\\-2+y_{2}=(-4)*2\\\\y_{2}=-8+2=-6\\\\\\\left \{ {{x_{2}=-1} \atop {y_{2}=-6}} \right.$

3/7÷1/2 how do you graph this

Luda [366]

3/7 divided 1/2 is the same as 3/7 times 2 which is 6/7.

Not sure what you mean by graphing it though. Like on a number line? There is no x or y in your equation.
