Answer:
(-2.5, 7)
Explanations:
The coordinates of the endpoint at A = (4.5, -3)
That is, (x₁, y₁) = (4.5, -3)
The coordinates of the midpoint at M = (1, 2)
That is, (a, b) = (1, 2)
Let the coordinates of the endpoint at B be represennted by (x₂, y₂)
The diagram representing the illustration is shown below:
The coordinates of the midpoint are given by the formulae:
x₁ = 4.5, a = 1, solve for x₂
y₁ = -3, b = 2, solve for y₂
The coordinates, (x₂, y₂) = (-2.5, 7)
The location of the other endpoint B is B(-2.5, 7)
