Solving by Graphing
Learn how to solve Solving by Graphing with clear steps and practice problems for Grade 9 algebra. Build confidence solving equations and checking your solutions.
Key Concepts
Property Graph each inequality on the same coordinate plane. The solution to the system is the region where the shaded areas of all inequalities overlap. Explanation It's like layering transparent colored sheets. The area where colors mix is your solution! Use a dashed line for $<$ or $ $ and a solid line for $\le$ or $\ge$. Examples For the system $y x$ and $y \le 4$, the solution is the area where the shading for both graphs overlaps.
