Find (Partial D w/Partial D y)_x and (Partial D w/Partial D y)_z at the point (w, c, y, z) = (18, 2, -1, -1) if w = 3x^2y^2 + 3yz - 3z^3 and x^2 + y^2 + z^2 = 6.

Choose the equation that represents the graph below: (1 point) graph of a line passing through points negative 3 comma 0 and 0 comma 3 y = x − 3 y = −x + 3 y = −x − 3 y = x + 3 will award !
