Write an equation for the line described. Write it in standard and point intercept form(if possible)
through (1,3), m=2
through (5,4), m=3/2
i need a little explanation also, if you can give it... studying for a test.

Best ResponseYou've already chosen the best response.0ok so you get those in standard form by first using this formula: \[(y  y_{1}) = m (x  x_{1})\]

Best ResponseYou've already chosen the best response.0so, for the first equation, this is (y  3) = 2(x  1)

Best ResponseYou've already chosen the best response.0to get it into standard form (Ax + By = 0) move 2x to the other side, giving you 2x + y  3 = 2

Best ResponseYou've already chosen the best response.0depending on qhat the quiz asks you, the final answer will either be 2x + y = 5 or 2x + y  5 = 0.

Best ResponseYou've already chosen the best response.0Did you mean slope intercept when you said point intercept?

Best ResponseYou've already chosen the best response.0So the second one. Standard form : y4=3/2(x(5))

Best ResponseYou've already chosen the best response.0And all those negatives are throwing me off..

Best ResponseYou've already chosen the best response.0Lots of people have trouble with it. We know that a negative negative is a positive. That gives you y  4 = 3/2(x + 5)

Best ResponseYou've already chosen the best response.0Then, you multiply x and 5 by 3/2

Best ResponseYou've already chosen the best response.0a positive and a negative multiplied together is a negative. That gives you 3/2x  15/2

Best ResponseYou've already chosen the best response.0Then I need to put it in standard form..

Best ResponseYou've already chosen the best response.0Well, that wasn't a complete point slope form, so let me explain. Above you gave me y  4 = 3/2(x  (5)) Your complete slope form would be y = 3/2(x  1), getting the 4 on the correct side. So, we'd have 3/2x + 3/2

Best ResponseYou've already chosen the best response.0Why dont you want it in the same form as the previous one? ax=by=0?

Best ResponseYou've already chosen the best response.0When I convert 4 into a fraction is that 8/2?

anonymous

Best ResponseYou've already chosen the best response.0When I subtract that 8/2 from the right side I come up with 3/2x7/2?

Best ResponseYou've already chosen the best response.0it's easier to set up standard form if you first have it in slope intercept form.

Best ResponseYou've already chosen the best response.0no, you want to get the constant on the right side of the equation BEFORE you multiply the whole thing by 3/2.

anonymous

Best ResponseYou've already chosen the best response.0Constant is a number with no variables; 3a would be a coefficient, 3 is a constant.

Best ResponseYou've already chosen the best response.0y4=3/2(x=5) can you take me from there?

anonymous

Best ResponseYou've already chosen the best response.0Okay. (you were right, I was getting confused.)

anonymous

Best ResponseYou've already chosen the best response.0first you add 4 to each side, giving you y = 3/2(x + 9)

anonymous

Best ResponseYou've already chosen the best response.0multiply both terms by 3/2, giving you 3/2x 27/2

anonymous

Best ResponseYou've already chosen the best response.0move 3/2x to the left side of the equation, giving you 3/2x + y = 27/2

anonymous

Best ResponseYou've already chosen the best response.0depending on the curriculum, your final answer would be 3/2x + y = 27/2 or 3/2x + y + 27/2 = 0

Best ResponseYou've already chosen the best response.0let me rewrite it out myself and see if that's the right answer

Best ResponseYou've already chosen the best response.0Do I just multiply by 2 to clear the fraction?

anonymous

Best ResponseYou've already chosen the best response.0no, when you're talking about lines you don't take out the fraction

anonymous

Best ResponseYou've already chosen the best response.0but let me work it out and see if I can get it that way multiplying by 2

anonymous

Best ResponseYou've already chosen the best response.0ok, it seems to me that your book does want you to multiply by 2, but my curriculum didn't teach me that
