Plotting Points on the Coordinate Plane

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

A pair of numbers (x, y) that define the position of a point on the coordinate plane.

The horizontal number line on the coordinate plane where y=0.

The vertical number line on the coordinate plane where x=0.

Quadrant I (x>0, y>0), Quadrant II (x<0, y>0), Quadrant III (x<0, y<0), Quadrant IV (x>0, y<0).

Quadrant IV.

Quadrant II.

The point (0, 0) where the x-axis and y-axis intersect.

Start at the origin, move along the x-axis to the x-coordinate, then move vertically to the y-coordinate.

Distance = √((x2 - x1)² + (y2 - y1)²).
