Front

What does a solid line represent in graphing inequalities?

Back

The points on the line are included in the solution set.

Front

What does a dotted line represent in graphing inequalities?

Back

Front

What is the general form of a linear inequality in two variables?

Back

Ax + By < C, Ax + By > C, Ax + By ≤ C, or Ax + By ≥ C.

Front

How do you determine the shading direction when graphing a linear inequality?

Back

Test a point not on the line; if it satisfies the inequality, shade towards that point.

Front

What is the solution set of an inequality?

Back

All the points that satisfy the inequality.
