How do you graph #y – 2x< 4 #?
1 Answer
graph{y<2x+4 [-10, 10, -5, 5]}
Explanation:
First we'll move the
Next, lets ignore the fact that there is an inequality, lets just see what happens if the
So lets graph this line. It looks something like this:
graph{y=2x+4 [-10, 10, -5, 5]}
But then we go back to the original equation and care about the
Subbing in
Because we know 4 is definitely bigger than 0, it means that (0,0) must lie in the coloured area! We now know to shade the area right of the line. But the question says
graph{y<2x+4 [-10, 10, -5, 5]}
And we're done.
