You do not have 3 coordinates in the Cartesian plane. The Cartesian plane is a plane and is therefore 2 dimensional. In 2 dimensional space you require only 2 coordinates. 3 coordinates are required to locate a point in 3-dimensional space but then it cannot be a Cartesian PLANE.
A point has coordinates (-3, 0). Where is it located in the coordinate plan?A point has coordinates (-3, 0). Where is it located in the coordinate plan?
It is [(3 + -13)/2, (3 + -13)/2] = [-10/2, -10/2] = (-5, -5)
Coordinates: (-4, 1) and (6, 3)Slope of line: 1/5
Points: (-1, 2) and (3, 3) Slope: 1/4
