Answer:

Step-by-step explanation:
Given that a recipe of chilie requires
cups of beans, to make
times the recipe, Keith would need x cups of beans.
Thus:
1 recipe =
cups of beans
of the recipe = x cups of beans




Therefore the equation that helps Keith find how many cups of beans he needs is: 
For this case we have the following inequality: y < 3x + 1 < br/ >
What we must do is to evaluate a point of the Cartesian plane and verify if it is in the shaded region.
The shaded region represents the solution of the system of equations.
For the point (0, 0) we have:
0 < 3(0) + 1 < br / >
0 < 0 + 1 < br / >
0 < 1 < br / >
Therefore, the point (0, 0) is in the shaded region because it satisfies the inequality.
Then, the points that are on the line, are not part of the solution because the sign is of less strict.
