Given:

The graph show relationship between the length of hallway Denise covers in tiles (x)

And the number of tiles needed (y)

AS shown: the relation begins from the point (0,0)

And the relation is linear

so, the relation between x and y are proportional

So, the answer is yes

Now, we need to get the relation:

The general form of the proportional relationship is : y = kx

So, using one point from the line to get the value of k

so, the line passing through the point ( 4 , 20 )

when x = 4 , y = 20

so,


\begin{gathered} 20=k\cdot4 \\ \\ k=(20)/(4)=5 \end{gathered}

So, the relation between x and y is :


y=5x

So, the constant is 5
