Answer 2

Instead of analyzing each choice, let's just graph the system and compare with the choices.
y >= -3x + 1
On a graph, place a point on y = 1

Answer 3

The slope is -3, so go down 3 and 1 right from that point. That's your second point.

Answer 4

Try point (1, 1) and see if it works in the inequality.
y => -3x + 1
Is 1 >= -3(1) + 1 true?
1 >= -2 is true, so area wit point (1, 1) is part of graph.

Answer 5

this is the graph of the first inequality. Now we graph the second inequality on the same graph.

Answer 6

y => 1/2 x + 3
We have a y intercept of 3. graph that.

Answer 7

Now we have a slope of 1/2. That means a rise of 1 and a run of 2. Let's do that to get a second point.
