Economics Help: Indifference Curves

Hi guys,

I know this is an economics question but im hoping someone can help me with this question:

David is confused. He has a limited income that he must allocate between his two favourite goods, A and B. David’s utility function for these goods is given by:

U(A,B)=4A+4B.

The price of good A is currently $6 and the price of B is currently $4.

a) Draw a graph indicating the indifference curves corresponding to level of utility equal to 24utils and 36utils.

Can someone help me with drawing this graph?

Your help will be appreciated :)
