What is a graph?
A graph shows the relation between a pair of variables (usually between x and y) where each is measured along the pair of axes at right angles.
How to graph:
When starting to graph, first start by drawing two axes that are perpendicular to each other like this:
The horizontal axis is called the x-axis and it is where you will identify all the points related to x.
The vertical axis is called the y-axis and it is where you will identify all the points related to y.
It is important to also understand that your graph must have units along the axis to mark the units.
For example if we were to graph the coordinates (2, 3) they are written in the form (x, y). First identify the x coordinate and then go up or down the vertical line at x=2 to find where y = 3 is and it will be marked where the blue dot is.
