 The correct option is (A). The image is attached below.

Step-by-step explanation:  We are given to graph the following equation on a  piece of paper:

Then, we are to select the correct choice of the graph that matches with the graph we have drawn.

Writing the inequality (i) as an equation, we get

Since it is a linear equation in two variables, so we need only two points to draw the graph.

At x = 0, we have

at x = -4, we have

So, (0, 2) and (-4, -1) are two points on the line.

We draw the line as shown in the attached figure below. Also, the line is dotted because the points on the line are not included.

Since so the region below the straight line will be shaded.

We see that the drawn graph below matches with the graph (A).

Thus, the correct option is (A).

step-by-step explanation:

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent
