Similar or not similar?

They are similar.

Step-by-step explanation:

All of the sides are of equivalent length (technically), the bigger triangle is just the smaller triangle doubled in size.

The linear inequality that is represented by the graph is:

From the graph of the given function we see that the graph is a solid line passing through (0,3) and (-6,0) and the shading is towards the origin.

Hence, we will check each of the given options.

A)

We see that the line of this inequality is a line passing through (0,4) and (-2,0) and shading towards the origin.

Hence, option: A is incorrect.

C)

The graph of this inequality is a solid line passing through (0,3) and (-6,0) and the shading is away from the origin.

Hence, option: C is incorrect.

D)

The graph of this inequality is a solid line passing through the point (0,3) and (-3/2,0) and shading away from the origin.

Hence, option: D is incorrect.

B)

When we plot the graph of this inequality we see that it matches the given graph.

           Hence, option: B is the correct answer.
