you have the hard work done!
y = -3x +18
add 3x to both sides
3x + y = 18
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...
How do I get it to the Ax+By=C form?
