Algebra 1 · Systems of Equations & Inequalities

Definition

Solving by graphing means graphing each equation and locating the intersection as the solution.

Teach it

Where it is taught, with guided notes, practice, homework, an exit ticket and an interactive Teacher Deck.

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.
