Exercise 39 Page 307

Use the Midpoint Formula.

(3,8)

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 A(3,0) and B(3,16). Let's use these to find the coordinates of the midpoint.

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

SubstitutePoints

Substitute ( 3,0) & ( 3,16)

(3+ 3/2,0+ 16/2)
