One of four parts into which the axes divide a coordinate plane. is an ordered pair (x,y) that produces a true statement when substituted a set of points that represent all solutions of an equation is a line graph Ax + By = C A & B cannot be zero A linear equation Ax + By = C, where the graph is not a vertical line

-x + 4 b = m = To solve for y, simply subtract the x from both sides Always write slope as a fraction Option 1 Slope-Intercept Form
