Algebra 1 · Systems of Equations & Inequalities
Definition
Solving by graphing means graphing each equation and locating the intersection as the solution.
Examples
- y = x + 1 and y = -x + 5 meet at (2, 3).
- Graph both lines and read where they cross.
Key rule
The intersection point is the solution to the system.
Memory hook
Graph both, the crossing point is the answer.
