 Linear equation in two variables any equation that can be written in the form ax + by = c, and a,b,c€R where a,b≠0 Horizontal line y=a where a€R (no x int.) Vertical line x=a where a€R (no y int.) Line through the origin ax + by = 0 where a,b€R ∆ (delta) the change in slope (m) ∆y/∆x = Y2 - Y1/X2 - X1 where (X1,Y1) & (X2,Y2) are points on a line standard form of linear equation in 2 variables Ax + By = C slope-intercept form of linear equation in 2 variables y = mx + b point-slope form of linear equation in 2 variables y - y1 = m(x - x1) linear inequality in 2 variables Ax + By (<,>,≤,≥) C
