The graph shows how the length of a buildings shadow at a certain time of day is related to the height of the building.

a. does the graph represent a relation? does it represent a function? explain why or why not?

b. write an equation to describe the relationship shown in the graph.

c. explain what variables in your equation represent.

A. the graph represents a relation because it contains ordered pairs (x,y). It is also a function because there are no repeating x values.

B. (0,0) (8,6)
slope = (6 - 0 ) / (8 - 0) = 6/8 = 3/4
so ur equation is : y = 3/4x or f(x) = 3/4x <===

C. the variable x represents the height of the building and the variable y (or f(x)) represents the total length of the shadow
