Question

Select the inequality that corresponds to the given graph.

Answer 1

The best thing to do, would be to set all of the equations so that y is on one side. Then it's just a matter of looking at them in y=mx+b form. If you find more than one equation with the same y=mx+b but they have different signs, you need to test points.

Answer 2

so the answer would be either A or B im guessing.. i am not the brightest at this.

Answer 3

We know by looking at it that it cannot be D, because the graph is dotted, so we wont even bother with it. We should now look at A, B, and C.

Answer 4

Let's take a look at A, we can simplify it to mx+b form.
\[4x-3y > -12\]
\[-3y > -12-4x\]
\[y < 4 + (4/3) x\]

Answer 5

it can also be written \[y < \frac{ 3 }{ 4 } x +4\]
notice the sign change when you divide by a negative number.

Answer 6

im sorry, that is suppost to be 4/3

Answer 7

thanks :) lol math is like chinese to me ;/ well atleast this.

Answer 8

graphing and stuff..
