Write an equation of a line that is parallel to 6x-3y=9 that contains the point (-5,-8)

In the form   Ax + By = C      [this is known as standard form ]

The slope is given by -A/B

So......A = 6    and B = -3

So....slope =   -6/ - 3  = 2

 

So.....since parallel lines  have equal slopes

 

We want to write a line with a slope of 2 passing through  (-5, -8)

 

Can you do it now, RP ???

I feel stupid for not knowing how to do this..

OK....we have

 

y = slope   ( x - x coordinate ) + y coordinate

 

y = 2 ( x -  - 5 ) - 8

 

y = 2 ( x + 5) - 8

 

y = 2x + 10 - 8

 

y = 2x + 2

I'd probably only be able to solve that with the equation
