Exercise 29 Page 411

Use the midpoint formula.

(0,7), see solution.

Practice makes perfect

To find the midpoint, we can use the midpoint formula. (x_1+x_2/2,y_1+y_2/2)The coordinates of the given endpoints are P(0,3) and Q(0,11). Let's use these to find the coordinates of the midpoint M.

M(x_1+x_2/2,y_1+y_2/2)

SubstitutePoints

Substitute ( 0,3) & ( 0,11)

M(0+ 0/2,3+ 11/2)
