Question

Find the midpoints of A and B where A has coordinates(8,2) and B has coordinates(3,8)

Answer 1

The midpoint is (5.5, 5)

Explanation:

The coordinates of the midpoint of a line is the arithmetic mean of the coordinates of the endpoints.

So for line AB whose end coordinates are (8,2) and (3,8):

Midpoint of x coordinate = mean of x coordinates

= (8+3)/2 = 11/2 = 5.5

Similarly, midpoint of y coordinate = mean of y coordinates

= (2+8)/2 = 10/2 = 5

So the coordinates of the midpoint (x,y) is (5.5, 5)
