The set is (1,3),(-1,2),(7,6)(adsbygoogle = window.adsbygoogle || []).push({});

it is in R2 so I dont get why there are 3 elements.

I assumed they are not vectors but points instead.

but if they are points then it becomes a line, and the answer is that its dimension is 2, and a basis is (1,0) and (0,1)

Could someone explain this?

Thanks
