Thread: Point Slope Form

Please help...totally confused!

Use point-slope form to write the equation of the line with the given properties. Write the equation in general form (Ax + By = C).
m = -3, passing through P(3, 9)

So I got to the point-slope form...
y=-3x+18
How do I get it to the Ax+By=C form?

THANK YOU!

you have the hard work done!

y = -3x +18

add 3x to both sides

3x + y = 18

A=3
B=1
c=18
