Question 26197: I need help with this question,
Find the equation, in standard form, of the line perpendicular to 3x-6y=9 and passing through (-2,-1) I'm a little confused on the standard form issue. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Sounds as though you know the slope of the given line is 1/2
So the slope of the line perpendicular to it is -2.
If m=-2 and the line passes through (-2,-1) you get:
-1=(-2)(-2)+b
b=-5
Equation of the line is y=-2x-5
Standard form is ax+by=c
Therefore rewrite your equation as 2x+y=-5 to put it
in standard form.
