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 To solve a system of equations by graphing, graph both equations on the same coordinate plane. The solution is the set of ordered pairs of the intersection points. Explanation Graphing is a visual treasure hunt! Just draw the line and the parabola. The exact spots where they cross are your solutions—the $(x, y)$ pairs that work for both equations. Examples For $y = x^2$ and $y = x+2$, the graphs intersect at the points $( 1, 1)$ and $(2, 4)$, which are the two solutions to the system.
