Re: graph the equation

start by drawing the line y = -x + 1

then (generic method when doing these things, although you can probably do it just by looking in this case)

take two points on either side of the line, and test the inequality, for the side where it holds, shade that side of the line.

Re: graph the equation

Luca's got it. So, in your case, you'd draw the line and shade below/to the right of it.

Also, it's conventional to draw the equation of the line as dashed when the inequality is strict (i.e, < or > instead of ≤ or ≥) to show that the line itself is not included in the region. Your inequality is strict, and so your line would need to be dashed.


Why did the vector cross the road?
It wanted to be normal.
