    Slope Intercept to Standard Form

    I have another problem on my math summer review hoping you can help.

    I need to convert this slope intercept equation to standard form(Ax+By=C) where the A is positive.

    Equation:
    Y=(-1/2)
    Y=(13/10)x


    Thanks in advance.

    EDIT: I also need help with this one, same type of problem.

    Y=(13/10)x

    Hi Mp5xm8

    Is this what you mean?

    y = - 1/2 ------------------> already in standard form where A = 0, B = 1, C = -1/2

    y = (13/10)x
    (13/10) x - y = 0 --------> A = (13/10), B = -1, C = 0

    or

    y = (13/10) x
    10 y = 13 x
    13 x - 10 y = 0 ----------> A = 13, B = -10, C = 0

    I'm not quite sure what you mean here. Since you mention slope-intercept, I'm guessing that perhaps the intercept is y = -\tfrac12, and the slope is \tfrac{13}{10}. Is that what you mean?

    If so, its ' y = mx + c' equation is

    y = \tfrac{13}{10}x-\tfrac12

    Multiply both sides by 10:

    10y = 13x - 5

    So the equation in the format you wanted is:

    13x -10y = 5
