Equation of a Line

Equation of a Line

1. Slope-Intercept Form

   • y = mx + c
     • General equation of a line y = y m = slope/ gradient x = x c = y- intercept
     • c = y-intercept
     • m = slope

2. Point Slope Form

   • y - y1 = m (x - x1)
     • y = y y1 = specific y value m = slope/gradient x = x x1 = specific x value
     • m = slope
     • y1 = specific y value
     • x1 = specific x value

3. Standard Form

   • Ax + By = C
     • A = specific number B = specific number x = x y = y C = specific number
     • A = specific value
     • B = specific value
     • C = specific value
