7. A curve in the zy-plane is described by the equation 2y(x − 1)² – xy² + 1 = 0. (a) Determine whether any of the points (x,y) = (1,0), (2,0), (1, 1), (2, 1) and (2,2) lie on the graph of this function. (b) For which of the points determined in (a) does the equation define y as an implicit dy function of r? Justify your answer. Evaluate the slope of this implicit function at dx these points.
