A point on the y-axis will always have an x-coordinate of zero. Instructions: In the figure above, the point with coordinates (4,2) is located in quadrant I. The point with coordinates (-3,4) is located in quadrant II.
The system shown at the right has no solution, as the grahs never intersect. On the other hand, the line and the parab. at the left do intersect, and the points of intersection are (-3,0) and (6,6).
