The linear equation that describes this relationship is y = (1/3)x

Linear equation

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line (rate of change) and b is the initial value of y.

Let y represent the actual size in inches and x the actual size in ft.

From the graph using the points (0, 0) and (4.5, 1.5):

y - 0 = [(1.5 - 0)/ (4.5 - 0)](x - 0)

y = (1/3)x

The linear equation that describes this relationship is y = (1/3)x
