Answer: First option.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope of the line and "b" is the y-intercept.
Observe in the graph provided that the line intersects the y-axis at this point:

Therefore, the y-intercept is:

Let's check each option:
1) 
Notice that:

2) 
You can identify that:

3) 
Observe that the y-intercept is:

4) 
Notice that:

Therefore, the equation that most closely represents the line depicted in the graph is:

Two rectangles should be shaded
They are similar because 4/2 = 8/4
It would b 9 x (-3^(x-1))
Answer: 108 ^m2
Step-by-step explanation:
you solve area by multiplying the base and height.
