How do i graph y=-x^2+3x-1 and 2y-1=x

Use stokes' theorem to evaluate c f · dr where c is oriented counterclockwise as viewed from above. f(x, y, z) = xyi + 5zj + 7yk, c is the curve of intersection of the plane x + z = 8 and the cylinder x2 + y2 = 81.

100 points and 1- -12=y-36 2- x/25=-25 3- -n=40
