In the XY plane, does the line with equation y=3x+2 contain the point (r,s)?
1. (3r+2-s)(4r+9-s)=0
2. (4r-6-s)(3r+2-s)=0

If K is a positive integer, is K the square of an integer?
1)K is divisible by 4
2)K is divisible by exactly four different prime numbers

OA=E

I was confused by statement 2. Four different prime numbers-does that mean four total (and different) as in [2,3,5,7] or can that mean [2,2,3,3,5,5,7,7]
