    I taught it was y=mx+b

    oh wait, do this formula y=mx+b and plug in the nimbers m is the slope b is the y intercept

    Yes I think I do, is it y=-3/4x-1 ?

    Well I plugged it in like y=1/4(-3)-1 and I multiplied 1/4 and -3 and got -3/4

    you have to get two lines in order to have an intersection point

    i think ur question should've been -1=1/4(-3)+b cuz the y coordinate is at -1

  17. Zale101

    m is the slope of the line and b is the y-intercept.

    x is the x coordinate given and y is the y coordinate given

    Then it'll be -1=-3/4+b

    No. And after that how do I know where to graph?

    Then the line equation must be "y = 1/4x – 1/4".

    the answer became confusing when we started doing the y=mx+b formula

    oh wait, that's not true if there's two coordinates we first do the the slope (y2 - y1) / (x2 - x1) and then put it in y=mx+b, sorry wrong formula

    (y-y1)=m(x-x1) (y--1)=1(x--3) y=1x--3+-1 y=1x+2 1x-y+2=0 here's what i got for the point-slope formula

  38. Zale101

    and the way we graph it was y=x+2

    if i were to use y=mx+b, the graph is y=1x-1
