By convention, 'x' is almost always the independent variable,
but it doesn't have to be.
Y-axis
It is called the abscissa.
(x,y) or (variable that cones first in the alphabet, variable that comes second in the alphabet)
Any ordered pair that makes the set true
On whichever variable is considered the y-variable. It would be the second element of each ordered pair of data points.
Y-axis
the first number in an ordered pair is the x coordinate it is one of the values that the independent variable has taken on
the first number in an ordered pair is the x coordinate it is one of the values that the independent variable has taken on
Ordered pairs are used to locate points on the graph. The first number in an ordered pair corresponds to the horizontal axis, and the second corresponds to the vertical axis.
The idea is to replace one variable in the equation by the first number in the ordered pair, the other variable with the second number in the ordered pair, do the calculations, and see whether the resulting expressions are indeed equal.

On whichever variable is considered the y-variable. It would be the second element of each ordered pair of data points.
It is called a graph. Graphs consist of many such points.
The point on a number line that corresponds to a number is called an "ordered pair" of a real number.
The numbers in the parenthesis represent the ordered pair for x and y. The x axis is horizontal and the y axis is vertical. When plotting the ordered pair, move across the horizontal axis for the first number and along the vertical axis for the second number.
