Question

1. Graph the system of inequalities. Then use your graph to identify the point that represents a solution to the system.

x > 3
y ≤ 2x – 5


A.
(5, 6)

B.
(4, –1)

C.
(–3, –1)

D.
(1, 11)

2. Graph the system of inequalities. Then use your graph to identify the point that represents a solution to the system.

x + y ≥ 5
x – 2y > 8

A.
(6, 1)

B.
(6, –2)

C.
(8, –1)

D.
(6, 2)

Answer 1

3.

Graph the system of inequalities. Then use your graph to identify the point that represents a solution to the system.

3x – 4y > 0
x – 5y > 0

A.
(6, 2)

B.
(–4, –2)

C.
(0, 0)

D.
(6, 0)

Answer 2

Just graph the straight lines and then use the inequality to note where to shade!

Answer 3

that don't tell me what (x, y) is

Answer 4

it does, if the given point lies in the shaded region, then its the solution!

Answer 5

i figured them out with a graphing calculator

Answer 6

you could have just plugged your answer choices into the inequalities and saw which satisfied the inequalities. For instance, the first one...
x > 3 ---- (4,-1)
4 > 3 -- correct

y <= 2x - 5
-1 <= 2(4) - 5
-1 <= 8 - 5
-1 <= 3 -- correct

answer is (4,1)

It is not that hard....just a little time consuming

Answer 7

thanks

Answer 8

but the question asks her to graph it.. !! u may lose points!

Answer 9

graphing will have to be done.

Answer 10

the teacher doesn't see the graphing

Answer 11

its online so she just shows us how to graph it

Answer 12

oh...really ? You might want to do the graphing anyways, just so you can learn how

Answer 13

she shows us how I just forgot so I need to go back and look at how she did it

Answer 14

good idea :)

Answer 15

thanks texaschick101

Answer 16

anytime :)
