A construction manager is monitoring the progress of the build of a new house. The scatterplot and the table show the number of months since the start of the build and the percentage of the house still left to build. A linear function can be used to model this relationship.

Which function best models the data?

• y = -13.5x + 97.8

• y = -13.5x +7.3

• y = 97.8x - 13.5

• y = 7.3x - 97.8

How can you use a line of best fit to make predictions about data?

• By finding the average of all data points

• By drawing it through the highest and lowest points

• By using it to estimate values for one variable given values of the other

• By counting the number of points that touch the line

What is the line of best fit in a scatter plot primarily used for?

• To separate different groups of data

• To predict the value of one variable based on the value of another

• To calculate the exact values of all data points

• To create a boundary around all data points

What is the primary purpose of analyzing relationships between variables in bivariate data?

• To create graphs

• To understand how changes in one variable affect another

• To collect more data

• To prove that the variables are unrelated

• The relation is a function.

• The relation is not a function.
