Question

Find the coordinates of the other endpoint of the​ segment, given its midpoint and one endpoint.​ (Hint: Let​ (x,y) be the unknown endpoint. Apply the midpoint​ formula, and solve the two equations for x and​ y.)
midpoint ​(11​,4​), endpoint ​(9​,1​)

Answer 1

Answer:

by mid point formula,

$\frac{9+x}{2}=11 \\ \implies x= 13$

similarly, $\frac{1+y}{2}=4 \\ \implies y,= 7$

endpoint is (13,7)
