Question

containers of gochujang, a korean chili sauce, are sold at a market. the scatter plot shows the relationship between the cost of 10 different containers and the amount of sauce in each container. a line of best fit is drawn through the data. based on the line of best fit, what is the approximate cost per ounce of a container of gochujang at the market?

Explanation:

Step1: Recall slope formula

The cost - per - ounce is the slope of the line of best fit. The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$.

Step2: Select two points on the line

Let's choose two points on the line of best fit. For example, $(8,4)$ and $(16,8)$.

Step3: Calculate the slope

$m=\frac{8 - 4}{16 - 8}=\frac{4}{8}=0.5$

Answer:

$0.5$
