Graphing Using Slope-Intercept Form
Graphing Using Slope-Intercept Form is a skill on Pengi from Lesson 56: The Slope-Intercept Equation of a Line in Saxon Math, Course 3.
Key Concepts
Property Before graphing a system, you should ensure equations are in slope intercept form ($y = mx + b$). Plot the y intercept $(0, b)$. Use the slope $m$ (rise/run) to find the next point. Special Cases : Horizontal lines are $y = c$ (slope is $0$). Vertical lines are $x = c$ (undefined slope).
Examples Convert to graph : For $3x + 2y = 8$, isolate $y$ to get $y = \frac{3}{2}x + 4$. Start at $(0, 4)$, go down 3 and right 2. Special lines : To graph the system $x = 5$ and $y = 3$, draw a vertical line at $5$ on the x axis and a horizontal line at $ 3$ on the y axis. They intersect at $(5, 3)$.
Explanation You cannot find a reliable intersection point if your initial graphs are inaccurate. Converting to $y = mx + b$ is the most efficient way to ensure your lines are graphed correctly before looking for a solution.
