Question 147913
Start with an empty graph. {{{y = -2/3x + 4}}} is already in y=mx+b form.  b is where you start on the y axis with your line, in this case 4.  plot one point on (0,4).  -2/3 is the slope.  This is also known as rise over run.  -2 is the change of the y axis, and 3 is the change on the x axis.  It can also be that 2 is the change on the y axis and -3 is the change on the x axis.  It doesn't matter, same line.


To plot the line, just start at (0,4), the point you've already plotted, and move in one of these two directions:


--to the right 3 and down 2 (over and over to plot points) or 
--to the left 3 and up 2 (over and over to plot points)


When you are done, your graph should look like this:
