Practice Problems

Find the coordinates of the Midpoint of a segment with the given endpoints. Start by substituting the coordinate values into the formula.

[(x sub 1 + x sub 2)/2,(y sub 1 + y sub 2)/2 ]

A = x1 , y1 and B = x2, y2

A(-3, 5) and B(5, -1)

[(-3+5)/2,(5+-1/2])]

(2/4), (4/2)

A(3.2, 7.8) and B(3, 1)

[(3.2+3)/2, (7.8+2)/2]

(6.2/2, 8.8/2)
