    write an equation of the line with x-intercept (-6,0)
    I am racking my brains...

    I need help on figuring out how to write an equation of the line with x-intercept (-6,0) and y intercept (0,-1)

    Please help me understand how to get this question answered and please show me step by step

    I think this is how to do it... but am not sure...

    find the slope first: m=y2-y1 which is -1-0 which is -1/6
    x2-x1 0-(-6)

    Since I know the slope is -1/6 I can use y= mx+b

    since I know the slope is also m and I know that the y-intercept is y

    then the equation should be the following: y=-1/6x-1

    does this look like the correct equation?

    First, find the slope. I assume you know how to do that. Difference in y's over difference in x's.

    Then, use y=mx+b. You're given b
