It was the French mathematician Rene Descartes who created coordinated geometry using an horizontal x axis and a vertical y axis that are perpendicular to each other
No. You're actually describing the 'Cartesian Coordinate System' invented by Rene' Descartes. He's such a fascinating person, you should treat yourself to a read about him. Check out the link below;
On an XY graph, the X axis and Y axis create four separate areas. Each one is a quadrant.
Yes.
When y=0 in any xy-coordinate, then the point will be on the x- axis. For example the point (1,0) is on the x axis with x=1.
legends a plane would be called the xy-plane if it had the x and y points on it Y axis
The line is x=0 otherwise known as the y-axis.
False
the example is a graph with an x and y axis
no. its an exponential with a vertical zero axis
To find the x-coordinate of a point on the xy-plane, you look at the horizontal distance of the point from the y-axis. The y-coordinate of a point on the xy-plane is the vertical distance of the point from the x-axis.
The x axis is read first when plotting points in the form (x,y) on the xy-plane.
