Hint: the y coordinates are the same, so you have a horizontal line
OpenStudy (anonymous):
so wouldjt it be C than?
jimthompson5910 (jim_thompson5910):
horizontal lines have a slope of 1/2 ??
OpenStudy (anonymous):
my bads its 0
jimthompson5910 (jim_thompson5910):
yep

OpenStudy (anonymous):
so thats my answer than right?
jimthompson5910 (jim_thompson5910):
yep
jimthompson5910 (jim_thompson5910):
that is correct
OpenStudy (anonymous):
I have another question real quick:
which point is contained in the graph of y>|x-2|-1?
jimthompson5910 (jim_thompson5910):
if the y coordinates are the same, then you have a horizontal line with a slope of 0

I have another question real quick:

jimthompson5910 (jim_thompson5910):
ok what are your points
OpenStudy (anonymous):
well here are the multiple choices to chose from:
A. 2,-1
B. 2, -2
C. 3,0
D. 2,0
OpenStudy (anonymous):
I got A for my answer
jimthompson5910 (jim_thompson5910):
let's find out if that's correct

jimthompson5910 (jim_thompson5910):
y>|x-2|-1
-1>|2-2|-1 ... plug in x = 2 and y = -1
-1 > |0| - 1
-1 > 0 - 1
-1 > -1
is that true?
OpenStudy (anonymous):
no lol maybe its B then
jimthompson5910 (jim_thompson5910):
plug in the coordinates and simplify
jimthompson5910 (jim_thompson5910):
if it's false, then it's not the answer
OpenStudy (anonymous):
hmm can you give me the problem to solve?

jimthompson5910 (jim_thompson5910):
y>|x-2|-1
-2>|2-2|-1 ... plug in x = 2 and y = -2
I'll let you finish
OpenStudy (anonymous):
i got no solution for that answer
jimthompson5910 (jim_thompson5910):
you should have gotten -2 > -1 which is also false
jimthompson5910 (jim_thompson5910):
so B isn't an answer either
OpenStudy (anonymous):
lol actually i think its C. kinda of a wild guess

jimthompson5910 (jim_thompson5910):
ok what do you get when you plug in x = 3 and y = 0
OpenStudy (anonymous):
no solution
OpenStudy (anonymous):
wait sorry hold on
OpenStudy (anonymous):
ya, I got no solution... 3>|0-2|-1
jimthompson5910 (jim_thompson5910):
what does the right side turn into?

a possitive
OpenStudy (anonymous):
right?
jimthompson5910 (jim_thompson5910):
|0-2|-1 = |-2|-1 = ???
OpenStudy (anonymous):
always true
jimthompson5910 (jim_thompson5910):
|0-2|-1 = |-2|-1 = 2 - 1 = 1

? so my answer would be D!!! right?
jimthompson5910 (jim_thompson5910):
oh wait, you plugged them in wrong
but yes, your answer is D
jimthompson5910 (jim_thompson5910):
somehow you managed to eliminate C, but not sure how you did that
OpenStudy (anonymous):
i just solved wat u gave me:)
jimthompson5910 (jim_thompson5910):
i gotcha
