I am confused please help

You have to give us a problem.
Write a problem you are working.
Then we can help: we do not guess!

From a quick search, Eliz's is probably the best: http://www.purplemath.com/modules/ineqgrph.htm

the question is 2x- 3y + 4 > 3

 

[stapel]

the question is 2x- 3y + 4 > 3

Solve to get "y" by itself on one side of the inequality. Draw the line for the equality (the "y=" line) and, in this case, draw it solid.

Then look back at your solved inequality. If it's a "y is less than" inequality, shade below the line; if it's a "y is greater than" inequality, shade above.

Note: There are worked examples at the lesson which was provided to you earlier.

So the answer is:
y < -1-2x / -3
is that right??

the question is 2x- 3y + 4 > 3

First, simplify the equation by moving the 4 to the other side (add -4 to both sides of the inequality).

Next, graph the line as though it were an equation instead of >. Make it a dotted line if there is no equality involved (neither >= or <=, strictly < or >). Then choose a point on one side of the line and see if its coordinates satisfy the inequality. If they make the inequality a true statement, then shade the side of the line that contains that point.

As Stapel said, since they want \(\displaystyle \geq\), shade above the line.
