Slope  of PQ =   [ 4 - -5 ] / [ 5 - -1] =  9 / 6  =  3 / 2

 

y =(3/2) (x - 5)  + 4        multiply through by  2/3

 

(2/3)y = x - 5 + 8/3

 

(2/3)y  = x  -  7/3           rearrange

 

x - (2/3)y  =  7/3           multiply by 3/7

 

(3/7)x - (3/7)(2/3)y = 1

 

(3/7)x - (2/7)y  =1

 

x / ( 7/3)   y  / ( 7/2)  = 1
