Linear Equations Two Variables

A linear equation in two variables can be written in forms such as $ax+by=c$ or $y=mx+b$. A solution is an ordered pair $(x,y)$ that makes the equation true.

Parameter questions for linear equations in two variables often use a given point, intercept, or slope condition to determine a missing coefficient.

Two-variable linear equations can be interpreted through intercepts, points on a graph, and context equations with two quantities.
