Question

How do you find a segment endpoint if you are given one end point of(12,-8)and a midpoint of (3,18)

Answer 1

$\left\{{{\frac{12 + x}{2} = 3}\atop{\frac{-8 + y}{2} = 18}}\right. \\\left \{{{12 + x = 3}\atop{-8 + y = 18}}\right. \\\left\{{{x=-9}\atop{y=26}}\right.$

End point of a Line Segment: (-9, 26)
