I am supposed to figure out if these are consistent or inconsistant ,but I am arriving at only one point for my answer, telling me this is constant but dependent am I doing something horribly wrong?
8x9y=63
9y8x=63

One equation can be derived from the other, by multiplying both sides by 1 and rearranging. They are consistent equations, and there is no unique solution. It is the same as having only one equation for two variables.

I think they are independent am I right?And would my answer be no solution or a point, my worksheet specifies for no solution, a point, and many solutions...I marked a point.

They are not independent. There are many (actually, infinite) solutions
