In her garden pam plants the tomato seeds inches below the ground after one mouth the tomato plants has grown a total of inches how many inches is the plant above ground

The answer rests on the two important pieces of data that belong in
the question.  The first one occurs after the word "seeds", and the
other one occurs after the words "a total of".

The answer is the difference between the two numbers.  Sadly, neither
number appears in the question, so a numerical answer can't be given.

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for

The variables should add up to equal 1
