Question 58931This question is from textbook
: Here's what i did:
the equation is 2-y=x-6. I'm trying to get it into standard form of a linear equation.
I subtracted 6 from both sides and came up with: 8-y=x.
I added 8 to both sides and got -y=x+8.
Then i subtracted y from both sides and came up with the equation x-y=8. did i do this right? and would the x-intercept be (8,0), and y-intercept (0,-8)?

Question 58932This question is from textbook
: This is the equation: 6x=y, and i'm trying to get it into standard form. Is it all right if i pretended there was a zero after the y, then the equation would read 6x=y+0?? I don't think it makes a difference but, anyways, as i was saying:
when i put in the zero i subtracted y from both sides and got the standard form of 6x-y=0. then i solved for the y and x intercept, and got (0,0) as x's, and (0,0) as y's. did i do this right?This question is from textbook

Question 58935This question is from textbook
: how would you write this standard form of a linear equation into slope intercept form?
-6x+7y=21. slope-intercept form is y=mx+b. so do you just plug the numbers in? would -6x+7y=21 in slope-intercept form be: y=-6x+21??This question is from textbook

Question 59409: What are some easy steps in solving 2 equations with 2 variables by canceling out one variable while adding both equations together? Apparently when you get your answer, it is suppose to be (x,y) form and nothing else. I am just so confused because the curriculum I have for homeschooling doesn't explain it very well. So, I am in need of some assistance if you can help! I hope I explained my delemma to where you understand it. Thank you...I hope I hear from you soon!

Thanks a bunch!

I am taking an Algebra class online and I am having problems understanding this unit. I am to do all odd questions because answers are in the back of the book. I am using the 2006 book Intermediate Algebra Third Edition by Alan S. Tussy and R. David Gustafson.
I attempted the problem by dividing 3x, then by dividing with 2y, but I do not come up with the correct answer of -3/2. I also can't figure out why this is negative. Could someone please help me? Thanks. I was okay until this whole slope of a line unit, now I am so confused.
