Given triangle ABC has vertices: A(−1, −3), B(4, −1), C(3, 4). What is the midpoint of segment BC?

Answer 1

Hi Aminata C

You can just use the midpoint formula to calculate

B(4, −1), C(3, 4). What is the midpoint of segment BC?

Midpoint Formula

(x₁₊ x₂/2, y₁, + y₂/2)

Let the coordinates of B = x₁, y₁ = (4, -1)

Let the coordinates C = x₂, y₂ = (3, 4)

Just plug them in

(4 + 3)/2 = x = 7/2 = 3.5

x = 3.5

(-1 + 4)/2 = y = 3/2 = 1.5

y = 1.5

So the coordinates of the midpoint of BC are (3.5, 1.5)
