Best Answer

You need to look at the graph first. The shape of the graph will give you hint as to what general form of equation would produce such a graph, then based on the numerical values for the dependent variable, you shouuld be able to figure out the exact equation or family of equations for the graph. For example what equation would produce a straight line, a curve--parabola, a circle, an eclipse, etc.? For your referance, you may review the (Conic Sections of Algebra or Precalculus). However, in higher level mathematics like Calculus, there are specific techniques in doing that but it's for me to discuss. Only well skilled mathematicians would discuss that for you. If you will, you may copy and past the particular graph you are referring to, together with the question exactly as it comes from your source.
