Introduction to Linear Inequalities

• What is a linear inequality?
• What do the symbols for inequality mean?
• What does <, >, <=, and >= mean?
• How do you graph linear inequalities on a number line?
• How do you graph x = 2 on a number line?
• How do you graph x < 2 on a number line?
• How do you graph x <= 2 on a number line?
• How do you graph x > -1 on a number line?
• How do you graph x >= -1 on a number line?
• How do you know when to draw an open or a closed circle on your starting point when graphing an inequality on a number line?
• How do you know which way the arrow of an inequality is supposed to point when graphing an inequality on a number line?
• How do you graph 2 < x on a number line?
• How do you graph -3 >= x on a number line?
• How do you change an inequality so the variable is on the left side of the inequality sign?
• How do you graph a compound inequality on a number line?
• How do you graph -2 <= x < 1 on a number line?
This is a very basic introduction to inequalities. This lesson starts a student off from the very basics of inequalities and graphing them on a number line. Whether the starting point should be a closed or open circle and which way to point the arrow is also discussed. This video is an excellent tutorial for learning inequalities.
