Question

What are the coordinates of the midpoint of AB? O (4, 13) O (5,0) 0 (43, 1) (4, 2)

Answer 1

To find the midpoint of AB, first find the coordinates of A and B

From the graph, A = (2,8) and B = (7, -5)

The midpoint of AB = 0.5 * { A + B }

so,

The midpoint of AB = 0.5 { (2,8) + (7, -5) }

= 0.5 * (9 , 3) = (4.5 , 1.5)

so, the coordinates of the midpoint = (4.5 , 1.5)
