Coordinates & Line Plots

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

Ordered pairs are pairs of numbers used to locate points on a coordinate plane, written in the form (x, y).

The x-axis represents the horizontal line on a coordinate plane.

The y-axis represents the vertical line on a coordinate plane.

The first number represents the position on the x-axis, and the second number represents the position on the y-axis.

The origin is the point where the x-axis and y-axis intersect, represented by the ordered pair (0, 0).

A line plot is a graph that shows the frequency of data along a number line.

To plot a point, start at the origin, move along the x-axis to the x-coordinate, and then move up or down to the y-coordinate.

A line plot helps to visualize data and see how often each value occurs.

The largest number in a data set is the maximum value.
