To learn "all the steps", please study how to solve for "y="
and how to graph linear equations
. You might also find it helpful to learn how to graph using slopes and intercepts
For instance, the first equation would be converted to y = 3x - 3, and then you'd graph.
Once you've studied the necessary background material, please attempt the exercise. If you get stuck, you can then reply with a clear listing of your steps and reasoning so far. Thank you!
