Question 695502: Need some help. I'm a parent trying to brush up on my alegbra to help my child. I can only get one of the answers to this problem. Need help with second part. Answers to choose from does not include what I get. Perhaps the correct answer isn't there and the teacher made a mistake...or perhaps it's me. Probgrlme is
A line passes the line (2,-1) and (8,4) a)write an equation for the line in point solpe form. b) rewrite equation in standard form using integers. For point slope I determined slope (y2-y2)/x2-x1 = 5/6. then used y-y1=m(x-x1) to get y+1=5/6 (x-2)..what is the standard form... Answer by vleith(2983) (Show Source):
You can put this solution on YOUR website! see this link on the various forms of equations for lines

The purplemath site is a great resource too.
Part B of this problem asks you to convert the answer you have in part A, into the general form (ax + by = c), where a,b and c are integers. Usually one expects a to be a positive integer.
So let's walk thru the whole thing
Use that value for to to solve part a
I suspect you're answer differs from the one given in the valueof the slope (m). Remember subtracting a negative numbers (minus a minus) ends up as a plus.
