Question 2 Point W has x-coordinate equal to –5. Can you predict the coordinates of point H which is on the line through W parallel to the y-axis? Which quadrants can H lie in? Let’s draw the Cartesian plane Since point W has x-coordinate –5, it can lie anywhere along the blue line Now, we have point H which is on the same blue line. So, point H could lie in 2nd Quadrant (if y-coordinate of H is positive) 3rd Quadrant (if y-coordinate of H is negative)
