Front

Is (3,-4) a solution to the system of inequalities?

Back

No

Front

Match the system to the graph: y > 3x and y < -2x + 4

Back

The correct match is y > 3x and y < -2x + 4.

Front

Solve the system of equations algebraically: -3x - 5y = -4 and y = 2x + 6

Back

The solution is (-2, 2).

Front

A rental car agency charges $30.00 per day plus $0.15 per mile. Another charges $36.00 per day plus $0.10 per mile. How many miles for equal cost?

Back

120 miles.

Front

What is the solution to the system of equations represented by the tables?

Back

The solution is (5, 11).

Front

Define a system of inequalities.

Back

A system of inequalities is a set of two or more inequalities with the same variables.

Front

What does it mean for a point to be a solution to a system of inequalities?

Back

A point is a solution if it satisfies all inequalities in the system.

Front

Explain how to graph a linear inequality.

Back

To graph a linear inequality, first graph the corresponding equation as a line, then shade the region that satisfies the inequality.

Front

What is the difference between a solid line and a dashed line in graphing inequalities?

Back

A solid line indicates that points on the line are included (≤ or ≥), while a dashed line indicates they are not included (< or >).

Front

How do you find the intersection of two linear equations?

Back

To find the intersection, solve the equations simultaneously to find the point where they meet.
