I believe there are 35 backpacks in all. 2 closets have 6 shelves all together. Then 6*5=35.
For this case we have that, by definition, the equation of a line in the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cutting point with the y axis
We have, according to the statement data that:

So, the equation is of the form:

We also have that the line intersects the "x" axis at -3, that is, the line passes through the point 
We substitute to find "b":

Finally, the equation is of the form:

Answer:

Base times height times length divided by 2
<span> D) Train A by a factor of 1.1
</span>Train A: <span>17/35</span><span> = 34.6</span>
<span>Train B: </span>Rate<span> is the </span>slope<span> of the </span>equation, 31.35
Thus,<span>34.6/31.35</span><span> = 1.1036</span>
