A question of Fit

I'd like to fit data of two independent variables, similar to the typical Fit[data, {1, x, y, TBD}, {x, y}] (data of the form {{x1, y1, z1}, {x2, y2, z2}, ..., {xn, yn, ) I have enough knowledge of the data to state that z [x, 0] = = x Is there a way to force a fitted function to pass through the known points at y = = 0?
