    these are the answers : y-1=6(x+5) y+5=6(x-1) y+1=6(x-5) y-5=6(x+1)

    you cant use this because you didnt know what is b (y-intercept)

    y=mx+b is slope-intercept form. This is point-slope form. You use point-slope form. All you do is plug in the numbers. That's all you do. Look at what I drew it explains it all. M is the slope and (x, y) is the point given.

    First, we find the y-intercept. -1 = 6(5) + b

    Once you solve for b, you have your slope (m=6) and y-intercept. I calculated it and found b= -1-30 = -31 y = 6x + (-31) therefore, y = 6x -31

    Do what Kymber did. That's another way to write the equation of a line. You end up with the same result.

    It says "point-slope form", that is not y=mx+b. The answer choices you gave are in point-slope form. I don't know why Brinethery is talking about slope-intercept form.

    This is point slope form: http://www.freemathhelp.com/point-slope.html Exactly what Kymber did.
