solve the system using substitution
i just told you how to do the other one; it's the same exact method. solve for x and y. you get: x=-2y+11 and y=(-1/2x)+(11/2). then plug them both back into the original equation (either one, it doesn't matter); you get, x=11, and y=0. the points would be (11,0)
thats not one of the options on the multiple choice though....
I'm so sorry, I put 11 where I should have put 13. The answer is A) 1,5. That's right. Sorry again.
