A construction manager is monitoring the progress of the build of a new house. The scatterplot and 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

Which graph best represents the solution set for this system of inequalities?

Which expression is equivalent to (n − 4)(2n + 7)?

• 3n + 3

• n − 28

• 2n² − 15n − 28

• 2n² − n − 28

Which expression is equivalent to (5rt − 3rw − 8tw) + (6rt − 4rw + 2tw)?

• 11rt + rw − 10tw

• 11rt − 7rw − 6tw

• 11rt + rw − 6tw

• 11rt − 7rw − 10tw

Two points are plotted on the grid.

Which equation in slope-intercept form best represents the line that passes through these two points?
