I believe it is 9. I think they are asking that if you plug in the y coordinate 0, and therefore it is asking what the value of x should be so that 2/3x-6 would equal 0. If you plug in 9, you get 18/3 and if you subtract 6 from that, you should get 0
sqrt (21) = sqrt(3)*sqrt(7)
is an irrational number
it cannot be simplified
it can be approximated
sqrt (21) is approximately 4.582575695.......
