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
