the broken lines means that its not equal to the equation so C and D out (not correct) ..

@freemap Do you know how to determine the right inequalities?

May I have example, I'm pretty sure I do Though

There are certain systematic ways to look at them. Would you me to show you?

@LynFran has shown one of the ways to eliminate choices. There are ways to actually find the answers.

I thought since one line is dashed it would be < or> Since solid line it world be>/ because its greater than or equal to

First, we look at the inequalities themselves. They are all identical, namely y=x+1 .....(1) has slope 1 and y-intercept 1. So that corresponds to the graphs. y=-2x-4 .....(2) has slope -2 and y-intercept -4, so that also corresponds to the graphs. That means the only criteria lie with the inequality signs. In this case, we have both dotted (strict inequality, > or <) and solid ((\le\) or (\ge\) ) lines, so that should be a first step.

* \(\le\) or \(\ge\)

The next step is to match the strict inequality, namely equation (2) is a strict inequality. where y>..... You will find that you choose the greater because you can look at the following drawing. |dw:1441116184475:dw|

I see

For inequality 1, we look at the drawing:|dw:1441116366366:dw|
mathmate
  • mathmate
So can you find the set of equation that satisfies both requirements? |dw:1441116467696:dw|
