Rotate the axes to eliminate the xy-term in the equation. Then write the equation in standard form. (Use xp for x' and yp for y' in your answer. Rotate the coordinate axes through an angle with 050 SR/2.) 2=4y 9x2 + 24xy+16y + 80x - 60y = 0 Check which variable(s) should be in your answer. Sketch the graph of the resulting equation, showing both sets of axes. y y y SP 2 -4 -2 4 2 2 - x X 2 4 -4 -2 2 -4 -2 2 4 C
