Question

which is the scatter plot for the data set {(1960,3), (1970,3.5), (1980,5), (1990,6)}?

Explanation:

Step1: Analyze the x - values of the data set

The x - values of the data set \(\{(1960,3),(1970,3.5),(1980,5),(1990,6)\}\) are \(1960\), \(1970\), \(1980\), \(1990\).

Step2: Analyze the y - values of the data set

The y - values of the data set are \(3\), \(3.5\), \(5\), \(6\).

Step3: Match with the scatter - plots

In scatter - plot A:

• When \(x = 1960\), \(y=3\); when \(x = 1970\), \(y = 3.5\); when \(x=1980\), \(y = 5\); when \(x = 1990\), \(y=6\)

Answer:

A.
