Question

for the in-n-out burger problem, we created the following equation below:
y = 1.75 + 0.90x
in the linear equation, the output of the total cost of the burger is represented by the value of select. while, the input of the amount of patties added onto the burger is represented by select. the starting value we represented as the initial cost of a single cheeseburger and was represented by the value of select. finally the constant increase is represented by the unit rate of select which is the price of one patty.

Explanation:

In a linear equation of the form $y = b + mx$, $y$ is the dependent/output variable (total cost here), $x$ is the independent/input variable (number of patties here), $b$ is the starting/initial value, and $m$ is the constant unit rate of increase.

Answer:

1. The output of the total cost of the burger is represented by the value of $\boldsymbol{y}$
2. The input of the amount of patties added onto the burger is represented by $\boldsymbol{x}$
3. The starting value (initial cost of a single cheeseburger) is represented by the value of $\boldsymbol{1.75}$
4. The constant increase (price of one patty) is represented by the unit rate of $\boldsymbol{0.90}$
