A line through the points (2, -9) and (j, 17) is parallel to the line 2x - 3y = 21. What is the value of j?

Slope of second line =  (-2/-3)  =    (2/3)

 

So....since the lines are parallel the slopes are the same......so....

 

[ 17  - - 9 ] /  [ j - 2 ]   =  2/3

 

26  =   (2/3) [ j -2]        

 

26 (3/2)  =  j - 2

 

39  =  j - 2

 

39 + 2  = j

 

41   =  j
