The midpoint of MN is point P at (-4, 6). If point M is at (8, -2), what are the coordinates of point N? O (-16, 14)
O (-10,5)
O (22)
O (6,2)

N(- 16, 14 )

Step-by-step explanation:

Given the endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ (x₁ + x₂ ), (y₁ + y₂ )

Use this formula and equate to the coordinates of the midpoint P

let the coordinates of N = (x, y ), then

(8 + x ) = - 4 ( multiply both sides by 2 )

8 + x = - 8 ( subtract 8 from both sides )

x = - 16

(- 2 + y ) = 6 ( multiply both sides by 2 )

- 2 + y = 12 ( add 2 to both sides )

y = 14

Thus

coordinates of N = (- 16, 14 )

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
