Standard Form (triangle)x+by=c Slope Intercept Form This is an equation of a line in the form y=mx+b. The m is the slope. The b is the y-intercept. Slope Formula The change in y or the change in x System of Equations one solution example infinitely many solutions example no solutions example This is two or more equations with common variables, also known as a linear system.
