Arbitrarily select #5# different values for #x#
then use the given equation to find corresponding #y# values
thus generating an ordered pair for each of your #5# selections.

Explanation:

Example:
Suppose we decide for our set of #x# values to use #{0,1,2,3,4}#

Using #y=-5x+4# to evaluate the #"corresponding "y# for each value of #x#:

#{: (underline(x),color(white)("XX"),underline("corresponding "y),color(white)("XX"),underline("ordered pair")), (0,,color(white)("XXXX")4,,(0,4)), (1,,color(white)("XXX")-1,,(1,-1)), (2,,color(white)("XXX")-6,,(2,-6)), (3,,color(white)("XXX")-11,,(3,-11)), (4,,color(white)("XXX")-16,,(4,-16)) :}#
