Example 1
Graph the equation y = Ix - 3I - 2.
Step 1. Determine the vertex of the equation.
The (h, k) of the equation, (3, -2), will be the vertex of the graph.
Step 2. Determine the a-value of the equation.
Since the a-value of the equation is 1, the slope of the line to the right of the vertex is +1 and the slope of the line to the left of the vertex is -1.
Step 3. Make a graph of the equation.
