Hi guys! I am desperately in need of help. I really need to do good on this test but I am uncertain if I am doing this portion correctly. Can someone check my work?
11. Which inequality matches the graph?
(The dot on the graph is at 1 and the arrow is pointing that way <-------)
A. 5x+6>11
B. 5x+6(underlined>)11
C. 5x+6<11*****************
D. 5x+6(underlined<)11
12. Which inequality matches the graph?
(The dot on the graph is at 2 and the arrow is pointing that way ---------->)
A. 5p+4>14*********
B. 5p+4(underlined>)
C. 5p-4>14
D. -5+4>14
11. C
12. A
I did not guess on those but I most likely got them wrong. I don't understand this topic. Thank you in advanced to anyone that helps me, I'm desperate. <3

wait, sorry I think the 2nd one is D
It is really quite simple
You are actually using the direction of the inequality symbol correctly
when you describe your graph.
When you said "pointing that way <-------)" , you described the symbol <
and of course > would show a directions -----> , or going to the right
11) 5x+6<11
5x < 5
x < 1 , so all values to the LEFT of 1, you were correct
12) 5p+4>14
5p > 10
p > 2 , which is "(The dot on the graph is at 2 and the arrow is pointing that way ---------->)"
and which was A, your original choice.
That's all there is to this
