Question 126435
This equations is written in the Slope intercept form {{{y=mx+b}}} with m being the slope and b being the y-intercept (0,b).

This equation can be graphed  straight from the equation.

First graph the y-intercept (0,-1)

Second, use the slope {{{(-2/3)}}} or {{{rise/run}}} to graph the next point.

Connect the point with a line.  All the coordinates that fall on the line are solutions to the equation.
