5.2 Special Cases of Linear Equations

Notes:

  • The equation for a horizontal line with y-intercept is y = k
  • ex. y = 3
  • The equation for a vertical line with x-intercept is x = k
  • ex. x = 3
  • In standard form, the equation to find the slope is – A/B
  • If slopes are negative reciprocals of each other, they are perpendicular
  • If slopes are equal, the lines are parallel
