Answer with explanation:
We have to find the mid point of the points P (-0.5,3) and Q(4,7.5) that lie on two dimensional coordinate system .Suppose mid point of PQ is R(x,y).
→Mid point of a line segment means that point on the line segment which divides the Segment in the ratio of 1:1.
→Mid point formula , point joining
is

→So, Mid point of line segment that has endpoints at (–0.5, 3) and (4, 7.5) is
.
