Give the equation of the line that is perpendicular to the line y= -3x + 7 and passes through point (0, -6)

please help
Answered by Reiny
your new line must have a slope of 1/3

so your new equation is
y = (1/3)x + b
sub in the given point to find b

I still don't understand this?
Answered by Reiny
Have you not learned that the slopes of perpendicular lines are opposite reciprocals ??

So if one slope is -3 , the other is +1/3

How would I get B?
Answered by Stuck
Plug the co-ordinates that you were given into the equation, and then you will only have 1 variable to solve for, which is b.
