Linear Equations in 2 Variables
Every time you see a straight line on a graph, you're looking at a linear equation in two variables. This topic is one of the most heavily tested on the SAT Math section, and for good reason. It connects algebra to geometry in a way that keeps showing up: slope, y-intercept, parallel and perpendicular lines, systems with one solution or none.
