I need 3 ordered pairs of points that would be solutions to this equation I have an idea of what suppose to fit because I think this equation has infinate solutions. What do you all think. Thank you!

4x - y = 7

It is a line. Yes, there are many points on a line, an infinite number.

There is one for every x you can think of, so try some like x = -1, x = 0, and x = 1

find the y from the equation for each of those x values. or for any other numbers like x = 5.7842789

Would (2,1) (3,5) (4,9) work to make this true? 4x - y = 7? X representing the first number in the pair, and y the second? Thanks!
