Convert      7         to rectangular form. Enter values so that fractions are simplified.

      r=   _______

           9sinθ−cosθ

We have

 

r = 7 / [ 9sin θ - cos θ]

 

r =  7 / [ 9(y/r) - (x/r)] 

 

r =    7r  / [ 9y - x]      divide out r

 

1 = 7 / [ 9y - x ]

 

9y - x  = 7

 

9y  =  x + 7

 

y  = (1/9)x  + 7/9
