Front

Which of the following is not a solution to this system of inequalities? (0,-1), (0,3), (4,0), (6,-2)

Back

(0,-1) is not a solution.

Front

Do I need to flip my sign? 2x -3y  ≥ 12

Back

Yes, you need to flip the sign when isolating the variable.

Front

How many solutions does a linear inequality in two variables have? 0, 2, 1, Infinite

Back

A linear inequality in two variables has Infinite solutions.

Front

What is a linear inequality?

Back

A linear inequality is an inequality that involves a linear function.

Front

What does the solution set of a linear inequality represent?

Back

The solution set represents all the points that satisfy 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 in the solution, while a dashed line indicates they are not.

Front

How do you graph the inequality y < 2x + 3?

Back

Graph the line y = 2x + 3 as a dashed line and shade below it.

Front

What does it mean to 'flip the sign' in an inequality?

Back

Flipping the sign means to reverse the inequality symbol when multiplying or dividing by a negative number.
