Unit 2.0 QAS 2.0 Quantitative Reasoning, Algebra, and Statistics (QAS) 2.5.1 Forms of Linear Equations The most common forms of linear equations are: Standard Form: Ax + By = C, in which the slope is given by and the y-intercept is given by . Slope-Intercept Form: y = mx+ b. Where the slope is m and the y-intercept is b. Point-slope Form: where the slope is m and is any point on the chosen line. ? =−? ? ? ?, ? − ??= ?(? − ?? ??,?? 1
