How do I graph this equation? y = -7/3x + 2

I can think of two ways to do it.

Way #1:

-- Pick a number.
   Write it in place of 'x', and calculate the value of 'y'.
   Call these 'x₁' and 'y₁'.

-- Pick another number.
   Write it in place of 'x', and calculate the value of 'y'.
   Call these 'x₂' and 'y₂'.

-- On your graph, mark little dots at the points (x₁, y₁) and (x₂, y₂).

-- With your ruler and pencil, draw a straight line between the two dots.
   Then extend it as far as you want to in each direction.

The line you drew is the graph of the equation.  
________________________________________

Way #2:

-- Looking at the equation, you realize that the slope of the graph is -7/3,
   and its slope is 2 .  Use this powerful information to draw the graph.

-- Mark a little dot on the y-axis, at the point where  y = 2 .

-- From that point, move your eyes 7 units to the right, then 3 units down,
   and mark a little dot where you land.

-- With your ruler and pencil, draw a straight line between the two dots.
   Then extend it as far as you want to in each direction.

The line you drew is the graph of the equation.

DaniilM [7]
3(x + 7) = 9(x - 1)
3(x) + 3(7) = 9(x) - 9(1)
  3x + 21 = 9x - 9
<u>- 3x          - 3x     </u>
          21 = 3x - 9
        <u>+ 9         + 9</u>
         <u>30</u> = <u>3x</u>
          3      3
         10 = x
