Answer 1

y≥3x

Remember, it has to be an inequality so an = sign will not work.

If you are graphing the inequality:

The line will be solid since it is ≥ and shade above the line.

Just graph like a regular y=mx+b slope.

So draw a point at (0,0) and then go up 3 and right 1, to (1,3) then go up 3 and right 1. Keep repeating this.

Answer 2

y>=3x
