Question

Which one describes the graph?????

Answer 1

The correct answer is C. y ≥ 3x -4

Explanation:

Let's observe the values for x, y, and 3x - 4 in the graph this way:

x 3x-4 y

-4 -8 Above the line and in the shaded area

-3 -5 Above the line and in the shaded area

-2 -2 Above the line and in the shaded area

-1 1 Above the line and in the shaded area

0 4 Above the line and in the shaded area

1 7 Above the line and in the shaded area

2 10 Above the line and in the shaded area

3 13 Above the line and in the shaded area

4 16 Above the line and in the shaded area

Then we can conclude that y ≥ 3x -4 because for any given value of x, y is always above the line and in the shaded area.

Answer 2

Option 3: y ≥ 3x + 4

Explanation:

The shade area represents the solution of an inequality

We should know the following:

The shaded area over a solid line if the the sign is ≥

The shaded area below a solid line if the the sign is ≤

The shaded area over a dashed line if the the sign is >

The shaded area below a dashed line if the the sign is <

For the given inequality:

the equation of the line 3x+4 and applying the previous rules

So, y ≥ 3x + 4
