Plotting graph with three variables

I want to draw a draw of a variable is in equation like

C(x,y)= ...... .

In this C is a variable and have 2 inputs with varying values.

I want to draw a graph between C and y. C is at y-axis or verticle axis and x is at x-axis or horizontal axis. But the curve like circle or elipticle on graph gives the value of y.

C value is claulated after submitting the different vlaues of x and y.

Assume x vary from 2, 4, 6, 8 and y = 3, 5, 7, 9. Now calculating C and draw graph. I am puzzled what to do?
