1x - y = 1?
Check your signs. You have a sign wrong... otherwise correct.
Not the answer you are looking for? Search for more explanations.
(and you don't need to put the coefficient "1" in front of the x)
Which sign do I have wrong? Can you explain why its wrong? @DebbieG
Can you show your work?
You started with the 2 points, (1,2) and (2,3).... what did you do first?
y - (3) = 1(x - 2)
y - 3 = 1x - 2
y - 3 = 1x - 2
-1x + y - 3 = -2
-1x + y = 1
1x - y = 1
Good. it all looks good.... until the final step.
What did you do, to get that pesky negative coefficient on the x, to be positive?
I multiplied everything by -1
Well, almost everything.
Everything on the left side, you did. ;)
-1! Thank you:)
exactly! :) and you're welcome. :)
@DebbieG Can I have your help with another question that i am a little confused about?
I can try to help, but you should really post each question separately. It looks like you're offline now and I have to go do some other things, but just post it as a new question, and someone will help! :) You can always tag me if you want, and if I'm online I'll try to help.
