    You have to do this first to find the slope\[\frac{ y^2-y^1 }{ x^2-x^1} \]

    I think I got the answer but I'm not sure. Is it y=2/6x+17/3 ?

    ok thats better! :) Next you have to find the equation y=mx+b First plug in the slope for m Then plug in on of the points for x and y Which will make you be able to find b

    Try this\[5=-\frac{ 2 }{ 6}(-2)+b\]

    This is what you should use\[5=\frac{ 2 }{ 6 }(-2)+b\]

    Yeah, that's what I did. After, I got 5=2/6(-2)+b and then I added 2/3 to both side and got b=17/3

    b should be\[5\frac{ 2 }{ 3 }\] Oh i see what you did, You kept it as a mixed fraction, but yes thats right
