4 0

Answer:

3x + 2y = 17

2x + 5 y = 26

Step-by-step explanation:

3x + 2y = 17 }

2x + 5 y = 26}

x - 3y = - 9

x = -9 + 3y

=> 2 (-9+3y)+5y=26

-18+6y+5y=26

-18+11y=26

11y=26+18

11y=44

y= 4

3x + 8=17

3x = 17 - 8

3x = 9

x = 9 : 3

x = 3

These are the options<br> (0,-5)<br> (4,-2)<br> (8,2)<br> (-16,-17)<br> (-1,-8)<br> (-40,-34)
Liono4ka [1.6K]
All you need to do is plug in the points!

Here we go:

3(0)- 4(-5)-8

If it equals 12, then it is a point and an answer. 

3(0)- 4(-5)-8= 12 

(0,-5) is a point!

Next one:

3(4)-4(-2)-8

12+8-8
That equals twelve. (4,-2) is an answer as well!

I am going to quickly plug in the rest of the points, since I think you have the idea. 
<span>(8,2)  3(8)-4(2)-8= 8 This is not an answer. 
(-16,-17)  3(-16)-4(-17)-8 = 12 This is answer. 
(-1,-8)      3 (-1)-4(-8)-8= 21 This is not an answer. 
(-40,-34) 3(-40)-4(-34)-8= 8 This is not an answer.
</span>
I hope this helped you!

Brainliest answer is always appreciated!
