Examine the data in the table below. The inputs and outputs represent a situation where constant rate can be assumed. Determine the equation that describes the function.
HINT* - Can you find the slope and y-intercept and write the equation that represents the function in y=mx+b form?
Examine the data in the table below.
- inputs (x) represent the number of bags of candy purchased
- outputs (y) represent the cost.
Determine the cost of one bag of candy, assuming the price per bag is the same no matter how much candy is purchased. Then, complete the table.
How much is each bag of candy?
Can you determine the value of the output (y) for an input of 𝑥 = −4? If so, what is it?
Hint - Work backwards on the table!
Does an input of -4 make sense in this situation?
Yes or No?
Explain.
