The reqd. ordered pair is#(6,17).#

Explanation:

Let the reqd. ordered pair be #(x,17)#, which by what is given, satisfy the eqn. #y=3x-1.#

Now, in our case, #y=17# satisfy #y=3x-1 rArr 17=3x-1 rArr 18=3x rArr x=6.#

The reqd. ordered pair is#(6,17).#

Alternatively, #(x,y)# satisfy #y=3x-1 rArr y+1=3x rArr x=(y+1)/3#.

For given #y=17#, from this we get #x=(17+1)/3=18/3=6.#
