Because of its uneven slopes across the graph, the tree does not develop at a steady pace.
In a proportional relationship, the ratio between the output variable y and the input variable x is constant, and is called constant of proportionality, given as follows:
k = y/x.
Then the equation is given as follows:
y = kx.
which, like in this instance, is a particular example of a linear function with zero intercept.
Three points from the graph given at the end of the answer are given as follows:
(0,0), (2,2), (7,10).
Given two points, the slope may be determined as follows as it is equal to the product of the changes in y and x.
Between (0,0) and (2,2): m = (2 - 0)/(2 - 0) = 1.
Between (0,0) and (7,10): m = (10 - 0)/(7 - 0) = 1.43.
Different slopes, hence the growth rate of the tree is not constant.
