Graphing Linear Equations
We know from geometry that through two points one and only one straight line can be drawn. Using this fact, it is enough for us to find two points and once we plot them we draw the straight line joining them.
Rule 1: To graph a linear equation we follow the steps below:
Step 1: Find the x- and y- intercepts.
Step 2: Plot the intercepts
Step 3: Draw the straight line joining the two points.
