• A line is increasing if it goes up from left to right. The slope is positive, i.e. m0

  

  .
• A line is decreasing if it goes down from left to right. The slope is negative, i.e. m0

  

  .
• If a line is horizontal the slope is zero. This is a constant function.
• If a line is vertical the slope is undefined
