This presentation shows how to plot a straight line graph from a horizontally aligned table of x and y values.
To plot a graph using a values table we follow these steps:
Step 1) Write the table out as a set of (x,y) coordinates.
Step 2) Rule up an X-Y grid on graph paper.
Step 3) Plot the points onto the grid.
Step 4) If the points from a pattern, then use a ruler to join the points together.
Step 5) Extend the line to fill the grid, and add arrows to both ends.
