Explain how to solve a system of equations using graphing.?

Question

This is a tutorial that might be helpful for college algebra students in Timothy Squires' class MyMathLab college algebra

Answer 1

In general, you're not always graphing lines because a system of equations might not (all) be lines.

 

And the system might not always be limited to two variables, either, e.g. 3 dimensions or even more (when you'll not be graphing).

 

In any event, wherever graphed functions intersect, you have points that satisfy all equations.
