Which of the following inequalities matches the graph? (Look at picture below) x > 4 x < 4 y > 4 y < 4
shaded area represents included values. So, do you think any values of x are excluded?
yes
@L.T.
x? Look at the graph. Where do you see an x that isn't included? I'm sorry if I confused you; I meant to lead you through the process of elimination
I think its x > 4, because it below the x
That's the y axis
Or wait is it y<4
Sorry i'm just confused..
Yes!
To your answer
I think the problem is that you confused the x and y axes. Vertical is y. horizontal is x
Oh! Haha okay.. can you help me with this one? Would it be y <= 0
These are the answer choices x <= 0 x >= 0 y <=0 y >=0
Yes, you've got it
What about this one? It's set up differently @L.T.
Choices The correct inequality is not listed. 5x + y >= 1 5x + y <=1 5x - y >= 1
In a special way this problem is almost the same as the others: perhaps you can figure out what I mean. The solutions are less than or equal to the line; so, in order to solve, you have to find the equation of the line.
5x - y >= 1
Right, and if you want to you can solve for y
