Thank you for explaining clearly what you need to know. You are given four answer choices. My strong suggestion is that you solve each one for x. This will take only a minute or two. Once you've done that, you'll likely see the connection to the given graph more easily.

  • anonymous
thanks but i already tried that and i still dont understand
mathmale
  • mathmale
Solve y+5>-2. show me your solution, please.
anonymous
  • anonymous
so i have to solve for y right?
mathmale
  • mathmale
yes. You said you'd already done this.
anonymous
  • anonymous
yes i tried understanding the graph by looking at the answer choices but i didnt really understand it
mathmale
  • mathmale
You aren't doing what I asked. I ask you to look at each of the four answer choices and solve each one for y. Are you willing to do that?
anonymous
  • anonymous
yes but i do not know how to solve for y that is also my problem
mathmale
  • mathmale
You've said you'd "already done that." Apparently you had not. This costs us time. If y + 5 > -2, subtract 5 from both sides.

Good. Now say in words what this symbolic relationship says.
anonymous
  • anonymous
y is must be bigger than -7
mathmale
  • mathmale
Very good. now, look at the graph. Can you find y=-7?
mathmale
  • mathmale
y+5>-2 is all in symbols and is therefore a "symbolic relationship."
anonymous
  • anonymous
oh ok and 7 is the circled one
anonymous
  • anonymous
so that would mean the answer is A right?
mathmale
  • mathmale
yes. Now: if we're talking about "greater than -7," do we circle -7 or do we put a dark dot on top of -7?
anonymous
  • anonymous
i have no idea
anonymous
  • anonymous
sorry
mathmale
  • mathmale
Not equal to : circle -7 Equal to dark dot on top of -7 Now look at y=-7 again. Would y=-3 be on the right side of y=-7 or on the left side?
anonymous
  • anonymous
the right side
mathmale
  • mathmale
Very good. Now answer A has already been re-written as "y>-7." Since we have the ">" symbol here, do we circle -7 or put a dark dot on top of -7?
anonymous
  • anonymous
circle
mathmale
  • mathmale
right. and " y > -7 " states that y is greater than -7. So, starting at your circle, should we go right or left?
anonymous
  • anonymous
Left because we are working with negatives
anonymous
  • anonymous
right sorry
mathmale
  • mathmale
No. We're comparing SIZE. if a number is greater than -7, it's on the RIGHT side of -7.
mathmale
  • mathmale
17 is greater than 13, so 17 appears to the right of 13, correct?
anonymous
  • anonymous
i said right look at the comment below
anonymous
  • anonymous
yes
mathmale
  • mathmale
Oh, I see. Next time, write, "to the right."
anonymous
  • anonymous
oh ok sorry my bad
mathmale
  • mathmale
so, putting together what we know, that is, that this set does not include -7 and all numbers in the set are greater than -7, which of the four answer choices is the best one?
anonymous
  • anonymous
A
mathmale
  • mathmale
Right. I know you chose A before, but I wanted you to know exactly why A is the correct choice.
anonymous
  • anonymous
ok thanks again (sorry i wasted your time not being clear0
mathmale
  • mathmale
Any questions about what we've done?
mathmale
  • mathmale
You didn't waste my time; we learned to communicate, and you succeeded in solving the problem. Nice working with you.
anonymous
  • anonymous
thanks you too
mathmale
  • mathmale
My pleasure. See you.
anonymous
  • anonymous
i have one more question with inequalities i will put it in a new thread it is like fraction things bye
mathmale
  • mathmale
thanks for doing that; I appreciate it. Helps keep things more orderly here. See you!
