It is the speed, which must be maintained at a constant value.

X divided by -Y is the same as -X divided by Y. Or - (X/Y)
It is represented in the form of (x, y) whereas x and y have given values
(x2 - y2)/(x - y) = (x + y)(x - y)/(x - y) = x + y
(-x)/(-y) = x/y as long as y does not equal 0 in which case it is undefined. x/y cannot be simplified further unless you are given values for x or y or both. For example, if x = 10 and y = 5 then x/y can be simplified to 10/5 = 2.
x=y
X goes into Y is really Y divided by X
You could show the y-axis by distance and the x-axis by time.
It is x^2 + xy + y^2
Y divided by X axix- Y/X
