Graphing a Quadratic Equation in Two Variables
To graph a quadratic equation in two variables, follow a systematic seven-step procedure:
Step 1: Write the quadratic equation with on one side. Step 2: Determine whether the parabola opens upward or downward. Step 3: Find the axis of symmetry. Step 4: Find the vertex. Step 5: Find the -intercept. Find the point symmetric to the -intercept across the axis of symmetry. Step 6: Find the -intercepts. Step 7: Graph the parabola by plotting the vertex, intercepts, and symmetric point, and connecting them with a smooth curve.
