Scatter Plot Check for Understanding

The scatter plot shows the sizes and annual rents of some office spaces in the downtown area of a city. What would the line of best fit reveal about these data?

• There is a strong positive relationship between the cost of rent and the size of the office space.

• There is a weak positive relationship between the cost of rent and the size of the office space.

• There is a weak negative relationship between the cost of rent and the size of the office space.

• There is a strong negative relationship between the cost of rent and the size of the office space.
