This graph shows the relationship between the pounds of cheese bought at a deli and the total cost, in dollars, for the cheese. Identify the constant of proportionality represented in the graph.

y = 4x

Step-by-step explanation:

formula is y=kx, where k is factor of proportionality

Looking at the graph where y and x meet...

2/0.5 = 4 so 2 = 4(0.5)

Therefore, 4 is k (constant)

4=4(1)

6=4(1.5)

10=4(2.5)

and so on...

if this is really you s much. i only have 3 points left and i have 2 questions to ask

no this is a nonlinear negative
