A Quick Review SALES The Daily Grind charges $1.25 per pound of meat or any fraction thereof. Draw a graph that represents this situation.

Identify the function shown by the graph.

A Quick Review Graph y = |x| + 1. Identify the domain and range.

Notes and examples

Notes and examplesGraph the system of equations. Then determine whether the system has no solution, one solution, or infinitely many solutions. If the system has one solution, name it.x + y = 3y = –x

Use the graph to determine whether the system is consistent or inconsistent and if it is independent or dependent. 2y + 3x = 6y = x – 1

Notes and examples

Use substitution to solve the system of equations.y = –4x + 122x + y = 2

Notes and examples

Use elimination to solve the system of equations.–3x + 4y = 123x – 6y = 18
