D Although the U.S. had ramped up its industry during the first world war, it still did not have its full industrial capacity maximized until 1942 during world war 2. It was not "the" world leader in industry, however it was on the top of the list
y≈2/3x+4/3
As you have the paralel equation, you can have the pending from it by turning the equation to the form : y=mx+b, where m=2/3
3y=-6+2x
y=2/3x-(6/3) which is y=2/3x-2
from here you have m= 2/3
then to construct the equation you use the formula with the point (-2,0) which is y-y1= m (x-x1), where y1= 0 and x1=-2 and following the formula you have:
y-0= 2/3 (x-(-2)) which results into: y=2/3 (x+2) and you turn it into an explicit ecuation by multiplying y= 2/3x+4/3, this way you have y=mx+b equation formula
