Caroline is hosting a friend's go away party.She wants to offer 1 bag of chips to each guest.The graph shows the prices for different numbers of bags. What is the constant of proportionality in terms of price per bag

Answer:
proportionality constant = $2 per bag
Step-by-step explanation:
Let the equation of the line representing relation between number of chips bags and total price of 'x' bags is,
y = mx + b
Here y-intercept b = 0 [Since this line passes through origin (0,0)]
Here 'm' = proportionality constant or price per bag
Equation will be,
y = mx
Now we select a point on the line that is (1, 2),
For a point (1, 2),
2 = 1 × m
m = 2
Therefore, constant of proportionality 'm' = $2 per bag
