I am given a question where I am asked to determine the most convenient test point used to determine if the points in a region defined by Y<1.4x+.6 satisfy the inequality are. I assumed the answer would be the point (0,0), but I am not 100% certain. Am I correct? Thanks

That depends entirely upon what you think is 'convenient'. Any point that is not on the boundary will work. The whole point is to pick a point that is easy to work with. Certainly it is NOT 'convenient' to waste a lot of time worrying about what is 'convenient'!

Like HOI said, "convenient" is in the eye of the beholder. Now (0,0) is definitely the easiest test point to use and in this instance 0 < 0.6 is TRUE so shade the region that includes the origin (0,0).
One thing to keep in mind, if your equation actually crosses through the origin, then you can't use (0,0) as a test point. (1,0) may be next easiest.
