In the xy plane does the line equation y=3x+2 contain the point (r,s)?
1) (3r+2-s)(4r+9-s)=0
2)(4r-6-s)(3r+2-s)=o
1) (3r+2-s)(4r+9-s)=0
2)(4r-6-s)(3r+2-s)=o
we can rephrase the question as ,is s=3r+2?
Statement 1 ---
either s=3r+2 or s=4r+9--->insufficient
Statement 2 ---
either s=3r+2 or s=4r-6--->insufficient
together s=3r+2 --sufficient
Ans C
please confirm.
