  2. use slope to do rise over run to get the second point

  3. Draw the line.

• 1. Make a table

  2. Plot slope and do rise over run

  3. Draw line

• 1. Plot two points

  2. Check the slope

  3. Draw line

• 1. Draw line

  2. Hope it is right

The line graphed on the grid represents the first of two equations in a system of linear equations.
