9. (a) A plane contains the point (1, -2,7), it is parallel to the y-axis and the x-slope is -5. Find the equation of this plane. (b) We move a point across the plane. The x-coordinate is increased by 2 units and the y-coordinate is decreased by 3 units. How does the z-coordinate need to change for the point to remain on the plane?
