Answer:

Se explanantion

Explanation:

Consider the equation #y=mx+c#

You can give any value you chose to #x# and the value of #y# depends on what value you give to #x#

So #y# is the dependant variable and #x# is the independent variable.

What you looking for is this: if the independent variable only maps to one value in the dependant variable then the equation/graph is that of a function.
