Best ResponseYou've already chosen the best response.2@LynFran has shown one of the ways to eliminate choices. There are ways to actually find the answers.

Best ResponseYou've already chosen the best response.0I thought since one line is dashed it would be < or> Since solid line it world be>/ because its greater than or equal to

Best ResponseYou've already chosen the best response.2First, we look at the inequalities themselves. They are all identical, namely y=x+1 .....(1) has slope 1 and yintercept 1. So that corresponds to the graphs. y=2x4 .....(2) has slope 2 and yintercept 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.

Best ResponseYou've already chosen the best response.2The 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
