Question

How do you determine whether each equation is a linear equation: `xy=6`?

Answer 1

ALL linera equations can be written in the form:

`Ax + By = C`

`xy=6` is not linear because x is multiplied by y not added so it cannot be written in standard for above, in fact `xy=6` is a hyperbola:

graph{xy=6 [-20, 20, -10, 10]}
