Question

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 1

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
