Me and my crew finish this test. answer this and we'll give you brainliest. we rlly need . only have 10 more minutes to finish this pl
given: line segment mp, with midpoint n.
point m is at (1, 3), and midpoint n is at (–5, 7).
find the coordinates of point p.
enter your answer as an ordered pair. ex: (x, y)

answer:

p(-11, 11)

step-by-step explanation:

first plug in all the points into the midpoint formula, which is, (x, y) = (x1 + x2/2, y1 + y2/2). but since the midpoint is already given, you plug in those coordinates into the (x, y).

(-5, 7) = (1 + x2/2, 3 + y2/2)

then split it up with the variables.

-5 = 1 + x/2

7 = 3 + y/2

let's solve for x first. so first you would multiply both sides by 2 and it cancels out on one of the sides, and the other, you get -5 × 2, which is -10.

-10 = 1 + x

then subtract 1 from both sides, and you get -11 as your x. now moving onto the y values, multiply both sides by 2 and it cancels out on one side and on the other you get, 7 × 2. that would be 14.

14 = 3 + y

then subtract both sides by 3 and you should get 11 as your y.
