Step 1: Substitute 0 for 
in the equation. Calculate the resulting value for 
. We'll call that 
for now (until you have actually substituted 0 for and have calculated the specific value for your given equation).
Step 2: Plot the point )
.
Step 3: Substitute 0 for in the equation. Calculate the resulting value for . We'll call that 
for now.
Step 4: Plot the point )
.
Step 5: Choose any number you like other than zero. Substitute the chosen number, call it 
for purposes of this discussion, for in the equation. Calculate the resulting value for . We'll call that 
for now.
Step 6: Plot the point )
.
Step 7: Draw the line that passes through all three of your plotted points.
