How do you write an equation for the line that is parallel to the given line and that passes through the given point: y=-3x;(3,0)

I know how to do this using point-slope form, but not with slope intercept form..

    very simple
    your new equation must be

    y = -3x + b , (the slope has to be the same, so the -3x part stays the same)

    sub in the given point (3,0)
    0 = -3(3) + b
    b = 9

    so y = -3x + 9

    thanks, Reiny.

    Emily, what about Angie?
