How do I write the equation of a line in STANDARD FORM, when it contains (-2,1) & (1,4) ?

  • algebra -

    First of all find the slope ...
    slope = (4-1)/(1 + 2) = 3/3 = 1 , how nice!

    using the point (1,4)
    y - 4 = 1(x-1)
    -x + y = 3

    x - y = -3

    Thank you so much!!!
    I have been staring at this problem forever, haha :)
    Thanks!
