THE STEPS FOR PLOTTING POINTS ON A GRAPH.
1. Make sure that you have variables (for ex. and )to work with (two columns
of data).x|y).
2. the variable is going to be represented on the
and the variable will be on the
3. Label the axes on your plot and determine the appropriate scale (if
the graph is not already labeled).
4. Begin by plotting the first two pairs of numbers (x,y) (the top row of
numbers).
a. First, find the value for on the .
b. Next, find the on the .
c. Your point should be plotted at the intersection of the
and the . (Draw one line vertically up from the x-value
and another line horizontally from the y-value, where they cross
is where you should put your (x,y))
d. Finally, plot the point on your graph at the appropriate spot.
5. Continue to plot pairs of points from the table (in rows) until you
have plotted all the points. (in case you have to plot a graph of linear function, you will need only 2 points because a line is defined with 2 points)
6. Your final graph should have the same number of points as pairs
of data in your table.

To plot a graph, first know what your input and output values are (usually x and y, but not necessarily).

Next, pick a set of x-values that make the function easy to evaluate. For example, if you are doing , you might pick x-values such as -2, -1, 0, 1, and 2. If you are doing a trigonometric function, picking values such as , , etc. can work.

Also, make sure you have picked enough points. If you know your equation is linear, two points is sufficient. However, you will need more points to graph other functions, including trigonometric and higher-order polynomial functions.
