The first number of the coordinate pair is the x-coordinate, and the second number is the y-coordinate. To plot each point, sketch a vertical line through the x-coordinate and a horizontal line through the y-coordinate. Their intersection is the point.
ⓐ Since x=−5, the point is to the left of the y-axis. Also, since y=4, the point is above the x-axis. The point (−5,4) is in Quadrant II.
ⓑ Since x=−3, the point is to the left of the y-axis. Also, since y=−4, the point is below the x-axis. The point (−3,−4) is in Quadrant III.
ⓒ Since x=2, the point is to the right of the y-axis. Since y=−3, the point is below the x-axis. The point (2,−3) is in Quadrant IV.
ⓓ Since x=0, the point whose coordinates are (0,−1) is on the y-axis.
ⓔ Since x=3, the point is to the right of the y-axis. Since y=25, the point is above the x-axis. (It may be helpful to write 25 as a mixed number or decimal.) The point (3,25) is in Quadrant I.
