(2,-1) x - 2y = 4 3x + y = 6 determine if the coordinate is a solution to the equations.

While the coordinates would be a solution to the first equation, they are not for the second equation, so the answer to your question is no.

Step-by-step explanation:

All you have to do is substitute the coordinates into the x and y values.

(2)-2(-1) = 2+2 = 4 We can tell that the coordinates worked for the first equation. Lets see if it works for the second, as well.

3(2) + (-1) = 6-1 = 5 Unfortunately, the coordinates were incorrect for the second equation.

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
