Consider the line in this graph:
  1. Identify a point visible on this line that has integer coordinates.
  2. What is the slope of the line?
  3. Use point-slope form to write an equation for this line, making use of a point with integer coordinates.
  1. The visible points with integer coordinates are and
  2. Several slope triangles are visible where the “run” is and the “rise” is So the slope is
  3. Using the point-slope equation is (You could use other points, like and get a different-looking equation like which simplifies to )
