Key idea: Graphing a linear equation
Three steps:
1. Find at least **two solutions** (preferably the and intercepts — easiest to plot).
2. Plot those points on the coordinate plane.
3. Draw a straight line through them.
Every linear equation in two variables graphs as a STRAIGHT LINE. (That's why they're called 'linear'.)
For accuracy: find a third solution and verify it lies on the line — catches arithmetic mistakes.
