Pick #3# arbitrary values for #x# and evaluate for corresponding #y# values to give #(x,y)# pairs.

Explanation:

For example if I choose
#color(white)("XXX")x in {0, 1, 2}#

#{:(underline(x),color(white)("XX"),underline(y=2x+1)), (0,,color(white)("XXX")1), (1,,color(white)("XXX")3), (2,,color(white)("XXX")5) :}#

Giving the ordered pairs
#color(white)("XXX")(0,1), (1,3), (2,5)#
