(1 point) The graph of the equation x2 + xy + 3/2 = 3 is an ellipse lying obliquely in the plane, as illustrated in the figure below. 9 dy .C t 7. a ompuedx d_y_ d): b. The ellipse has two horizontal tangents. Find an equation of the lower one. The lower horizontal tangent line is defined by the equation y = c. The ellipse has two vertical tangents. Find an equation of the rightmost one. The rightmost vertical tangent line is defined by the equation x = d. Find the point at which the rightmost vertical tangent line touches the ellipse. The rightmost vertical tangent line touches the ellipse at the pojnt
