34.) A (0,0) B 90,4)

36.) A (3,3) B (3,-3)

38.) A (3,0) B (1,4)

**Steve**, Sunday, December 2, 2012 at 2:17pm36 is easy, since AB is vertical.

34 and 38 are done the same way:

find the midpoint of AB

find the slope of AB; you want the negative reciprocal.

Now you have a point and a slope; the equation is easy

#38:

midpoint of AB is (2,2)

slope of AB is -2, so slope of ┴ is 1/2

y-2 = 1/2 (x-2)

now just pick any two values of x or y and solve for the other (y or x)
