The coordinate plane, also known as the Cartesian plane, is a two-dimensional system used to locate points. It consists of two perpendicular number lines, the x-axis, and the y-axis, which intersect at their zero points, called the origin.
Points on the coordinate plane are located using ordered pairs (x, y), where x represents the horizontal position along the x-axis, and y represents the vertical position along the y-axis.
To plot a point, locate the x-coordinate on the x-axis, then move vertically to the y-coordinate on the y-axis, and mark the point at their intersection.
The distance between two points on the coordinate plane can be found using the distance formula: √((x2 - x1)^2 + (y2 - y1)^2).
