Answer:

Therefore C is not the midpoint of AB.

Explanation:

Midpoint: The midpoint is a point from which the distance between the endpoints of a line segment is always equal.

Distance formula:

The distance between the points (x₁,y₁) and (x₂,y₂) is


√((x_2-x_1)^2+(y_2-y_1))

Given points are A(2,3) and B(-2,5).

If C(0,3) is the midpoint of the line segment AB,then AC=BC.

The distance between AC is


√((0-2)^2+(3-3)^2)


=√(2^2)

=2 units

The distance between AC is


√((0-(-2))^2+(3-5)^2)


=√(2^2+2^2)


=4√(2) units.

Since AC ≠ BC

Therefore C is not the midpoint of AB.
