Question

Find the other endpoint given endpoint (-10,7) midpoint (6,2)

Answer 1

(22;-3)

Explanation:

if to calculate the coordinates of the given midpoint it needed to use:

`x_(midpoint)=(x_(endpoint1)+x_(endpoint2))/(2);`

`y_(midpoint)=(y_(endpoint1)+y_(endpoint2))/(2);`

then to calculate the coordinates of endpoint2, it needed to perform the substitution:

`(-10+x_(endpoint2))/(2)=6,`

`2=(7+y_(endpoint2))/(2),`

finally:

`x_(endpoint2)=22;`

`y_(endpoint2)=-3.`
