I'm seeing a lot of this kind of question (ordered pairs that satisfy an equation). Apparently this is an approach favored by Common Core revisionists. It is highly over-rated.
This equation is a linear equation; it can be solved for y, giving y = mx + b, which is called the slope-intercept form.
For a straight line (which this is), you can pick ANY value for x, plug it in, and get a resulting associated value for y.
If you have been given a list of ordered pairs, you may test each of them to see if they satisfy this equation.
It would be better to approach this topic as Graphing Lines--learning about intercepts and slope.
The "find which of these lists of ordered pairs is right for this line" approach is not very good--and it missed fundamental concepts.
