Y= 3x; (2, 6) is this a solution or not?

Yes. If you substitute 2 for x, 3x would equal 6. If you substitute y for 6, then you would get 6 = 6 which means that that is a solution to the equation

Yes, this is a solution.

Because    y = 3x

                 6 =  3 × 2

                 6 = 6

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)
