It tells the point’s horizontal distance from the y-axis. 4 Plot 5 Ordered Pair: a pair of numbers, (x, y), that describes the location of a point in the coordinate plane. The x-coordinate gives the point’s horizontal distance from the y-axis, and the y-coordinate gives the point’s vertical distance from the x-axis. 6 Absolute Value: A number’s distance from 0 on the number line. Absolute value is never negative. 7 y-coordinate: the second number in an ordered pair. It tells the point’s vertical distance from the x-axis. 8 Reflection: A transformation that flips (reflects) a figure across a line to form a mirror image. 9 x-axis: the horizontal number line in the coordinate plane. 10 Quadrants: The four regions of the coordinate plane that are formed when the x-axis and y-axis intersect at the origin. 11 y-axis: the vertical number line in the coordinate plane. To connect one thing to one or more other things. To mark where something is, for example on a map, graph, or number line.
