2.6 Intro to Solving Systems of Inequalities

Front

If the inequality symbol is > or \ge, you shade ________.

Back

above

Front

If the inequality symbol is < or >, the line will be _________.

Back

dotted

Front

What type of line is used for inequalities that include \ge or \le?

Back

solid

Front

What does the solution to a system of inequalities represent?

Back

The region where the shaded areas of all inequalities overlap.

Front

How do you determine which side of the line to shade for the inequality y < mx + b?

Back

Test a point not on the line (usually (0,0)) to see if it satisfies the inequality.

Front

What is the graphical representation of the inequality y \ge 2/5x + 1?

Back

A solid line with shading above the line.

Front

What is the graphical representation of the inequality y < 3x - 2?

Back

A dotted line with shading below the line.

Front

Which inequality describes the graph of a line with a slope of 3 and a y-intercept of -2 that is shaded above?

Back

y > 3x - 2

Front

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

Back

A solid line indicates that the points on the line are included in the solution (\ge or \le), while a dotted line indicates they are not included (> or <).

Front

How do you solve a system of inequalities by graphing?

Back

Graph each inequality on the same coordinate plane and identify the overlapping shaded region.
