Question 306858
SAMPLE:

Find two points in the (x,y) for y = x + 3.

Select different values for x.  Any value at all.

I will let x = 0 and then let x = 2.

When x = 0, y = 0 + 3 becomes 3 making y = 3.

Our first point is (0,3).

When x = 2, y = 2 + 3 becomes 5 making y = 5.

Our second point is (2,5).
