Modeling Real-World Problems with Linear Functions: Sample Algebra 1 EOC Questions

Rental fees, phone plans, savings accounts, and depth-per-minute problems are all linear models. Students solve them, interpret the slope and intercept in the units of the story, and decide which part of the graph the situation actually allows.

How the Algebra 1 EOC tests this benchmark

This benchmark is drawn twice on a practice form because it is one of the most heavily represented on the real test. The equation or graph is always given, and a graphing item always asks for something more than the picture: a solution, an interpretation, or a constraint. Constraint questions ask which values of the domain make sense, such as whole numbers of tickets.

Skills students need

Interpret slope and intercept in context
Solve a real-world problem with a linear model
Determine reasonable domain constraints
Read a solution off a modeled graph
