The midpoint of M(4, -1) and N(x, y) is P(3, -4). Find the coordinates of N.
Answer Details
We know that the midpoint of a line segment is the point that is exactly halfway between the endpoints of the segment. So, to find the coordinates of point N, we need to use the midpoint formula.
The midpoint formula is:
Midpoint = [(x1 + x2)/2, (y1 + y2)/2]
where (x1, y1) and (x2, y2) are the coordinates of the two endpoints of the segment.
In this problem, we are given that the midpoint of segment MN is P(3, -4), and one endpoint is M(4, -1). Let's call the coordinates of the other endpoint N(x, y). Using the midpoint formula, we can write:
[(4 + x)/2, (-1 + y)/2] = (3, -4)
Now, we can solve for x and y:
(4 + x)/2 = 3 => 4 + x = 6 => x = 2
(-1 + y)/2 = -4 => -1 + y = -8 => y = -7
Therefore, the coordinates of point N are (2, -7). So, the correct option is (2, -7).
