Question

Which expressions can be used to find the coordinates of the midpoint of PQ with endpoints P(3, –1) and Q(–7, –6)? Select three options.

can be used to find the x-coordinate of the point.
can be used to find the y-coordinate of the point.
(–7 – 3) + 3 can be used to find the x-coordinate of the point.
(–6 – 1) – 1 can be used to find the y-coordinate of the point.
– 1 can be used to find the y-coordinate of the point.

Answer 1

Answer:

To determine the midpoint of a line segment with the given endpoints, one should determine the averages of the coordinates of the points.

x-coordinate: (3 + -7) / 2 = -2

y-coordinate: (-1 + -6) /2 = -7/2

Hence, the coordinates of the midpoint of the line segment are (-2, -7/2).
