    Well, do you know in the equation of a line \[y=m(x-h)+k\] what each letter means?

    Well, let's try to figure it out. How about this. Given two points, what's the slope of the line they make?

    y=mx+b

    No... that's an equation for the line. How about you tell me this. If you have \[p_1=(x, y)\] and \[p_2=(h, k)\], then what is the slope s you get between them?

    she just gave the slope, so that's a line

    all she has to do is plug it in the slope-intercept formula

    Okay, @candrie , when you're at the y-intercept, what's the coordinate pair?

    If a point is on a line, then its x and y values, when inserted into the formula you gave,\[y = m x +b\], must hold true.

    So put in the y-intercept's values into the formula.

    Well, I was trying to get you to say: 6=m(0)+b, so b = 6. But since you know what b and m are already, what's your question?

    Well it is y = m x + b. The difference is that my equation is y = m (x - h) + k But they're really the same because y = m x - mh + k y = m x +(k-mh) and k-mh =b
