Question 251031: graph: y is greater than or equal to 3x+2
use -2, -1, 0, 1 and 2
Answer by drk(1908)   (Show Source):
You can put this solution on YOUR website! Y is greater than or equal to 3x + 2
let's create coordinates: (X,Y): (-2,-4), (-1, -1) (0, 2) (1, 5), and (2, 8)
Plot these coordinates on your coordinate plane.
Since it says "equal to" draw a solid line through your dots.
Next, we shade. Since we have "greater than" we shade up or away from you.
If you want to pick a test point, that is a good w way to check. Suppose we choose (1,6).
6 >= 3(1)+2
6>=5 [true]. If true shade that region.
