Question

M is the midpoint of JK. Find the coordinates of K. J(0, 11), M(-3,2)

Answer 1

Let's assume

point K as (x,y)

M is the midpoint of JK

so, other point as J(0, 11)

M(-3,2)

`(-3,2)=((0+x)/(2),(11+y)/(2))`

now, we can compare both sides

Calculation of x-coordinate:

we get

`-3=(0+x)/(2)`

`x=-6`

Calculation of y-coordinate:

we get

`2=(11+y)/(2)`

`11+y=4`

`y=-7`

so, we will get point K

K=(-6,-7)............Answer
