plane xy
True.
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.
If Y = 0 then there is no value of X such that XY = 1.
It would depend upon your coordinate system. But in the regular Cartesian (rectangular) coordinate system you used in high school, the x axis is left to right and the y axis is up and down. So the vertical plane would be the xy plane. If you are in three dimensions, the x axis is forward and backwards (coming out of the page toward and away from you), the y axis is left and right, and the z axis is up and down. So you would have two vertical planes--the xz plane and the yz plane.

True.

x = 4 is a straight line that is vertical when plotted on the xy graph, where y is the vertical axis and x is the horizontal axis. A vertical line has an infinite slope; the slope is infinity
When x = 4 is graphed in an xy plane, it is easy to see why a vertical line is formed. At every value of y, x = 4. Plot enough points like this on your graph and you will soon form a vertical line.
If Y = 0 then there is no value of X such that XY = 1.
no, coordinate graph is a graph made on a coordinate plane i.e xy-plane
It would depend upon your coordinate system. But in the regular Cartesian (rectangular) coordinate system you used in high school, the x axis is left to right and the y axis is up and down. So the vertical plane would be the xy plane.

So you would have two vertical planes--the xz plane and the yz plane.
In an xy-graph, also known as the cartesian coordinate plane, the x-axis is the horizontal line, and the y-axis is the vertical line. The x-axis is often associated with distance, time, velocity, acceleration, newtonian forces, and hundreds of other metrics.
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;
Form a right angle triangle under the slope and divide the base of the triangle into the height of the triangle.
