See a solution process below:

Explanation:

Pick a number for #x#, any number!

Then substitute the number you picked for #x# and evaluate the right side of the equation. The number you picked and the result of the right side of the equation will give you and ordered pair:

First Ordered Pair:

  • Pick a number for #x#, any number: I pick #10#

  • substitute the number you picked for #x# and evaluate the right side of the equation.

#y = 2x + 5# becomes:

#y = (2 * 10) + 5#

#y = 20 + 5#

#y = 25#

  • The number you picked and the result of the right side of the equation will give you and ordered pair:

#(10, 25)#

Second Ordered Pair:

I will pick: #22#

#y = 2x + 5# becomes:

#y = (2 * 22) + 5#

#y = 44 + 5#

#y = 49#

#(22, 49)#

Try this three other times to get your 5 ordered pairs.
