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)
