How can I write an equation of the linefor example (2,-7) 8x +3y=2. I keep mnissing the most important step. Some of these I have done quite well, like x+6y=9. Please help with the detail because I do remember when to divide.

    Equation of a line requires either:
    a. two points
    b. one point, and a slope

    What exactly are you trying to do?

    I am trying to wite the equation in the form
    y=mx+b

  • math116 - ,

    The equation has two given point (3,-8), then an equation Example (3,-8) 8x +3y=6(just an example)


    For example (8,5) 8x+3y=7
    y-y=m(x-x)
    y-5=m(x-x)
    y-5=3/8(x-)
    =3/8x-8
