Write an equation of a line that passes through the point (9, -3) and is parallel to the following equation: 9x + 7y = 330

9x  +  7y   =   330

The slope of  this line =  - (9/7)

 

So

 

y = (-9/7)(x - 9)   - 3

 

y  = (-9/7)x  + 81/7  - 3

 

y =  (-9/7)x  + 81/7  - 21/7

 

y = (-9/7) x  +  60/7      

 

7y   =  -9x  + 60

 

9x + 7y   =   60
