Question 830107: Hi, I've been having trouble solving this question on my test review for class.
The points (-2, 11) and (6, 3) lie on the same line. What is the x intercept of the line?
A. (-2, 0)
B. (0,9)
C.(9, 0)
D. (-1, 0)
I'm not quite sure how to go about solving this. I've already tried finding the slope of the line the two points rest on and solving y=mx+b. But that got me no where and I'm well and truly stumped. Please help me if you can. Thank you. (In my text book the section the problem is under is standard form. That section is in the chapter called linear functions. I hope this helps.)

Question 831056: In problems like (-31xm) + -2 =618 why do you bring the -2 over first? I can't figure out why sometimes it is the parenthesis and sometimes just the number. I thought it was order or operations but this doesn't seem to apply, it is not the parenthesis or the times part. It is the adding/subtracting you do first. How do you know????
