find distance between each pair of points.
(5,3) & (5,-3)
Hi Kiona, as I bet you already know, point coordinates (locations on the X and Y axes of a graph) are listed as X first, then Y. The first set (5,3) means at that point, X=5 and Y=3. The second set (5,-3) means that X=5 and Y=-3
Usually the X-axis is a horizontal line, and the Y-axis is vertical, crossing the X-axis perpendicular (at right angles). The point (0,0) is where the X and Y axes meet each other (cross).
Since both points have X=5, both points are equally distant (+5) from the Y-axis, and therefore a line through those two points is a straight line parallel (same direction as) the Y-axis, crossing the X-axis at X=+5. Draw it yourself so you can see it - makes it much easier to understand!
One point is +3 above the X-axis, and the other point is -3 below the X-axis. Therefore, the total distance must be 6.
