AD is the diagonal of a 6 by 15 rectangle,

31.


AD^2 = 6^2+15^2=36+225=261 = 9(29)


AD=3 √(29)

Choice A

32.


d^2 = 2^2+3^2=4+9=13


d=√(13)

Choice A

33.

7 - 4x = 7y

4x + 7y = -7

The parallel through (2,0) keeps the coefficients on x and y and just changes the constant:

4x + 7y = 4(2)+7(0)= 8

7y = -4x + 8

y = (-4/7) x + 8/7

Choice B
