This video tutorial covers one and two-step inequalities, explaining the symbols used and how to graph them on a number line. It also demonstrates how to write inequalities from graphs and solve them using similar steps to solving equations, with an added step of flipping the inequality sign when multiplying or dividing by a negative number.

What is the main objective of today's lesson?

• To solve and graph quadratic equations

• To solve and graph one and two step inequalities

• To solve and graph one and two step equations

• To solve and graph linear equations

What does the symbol '≤' represent?

• Greater than

• Greater than or equal to

• Less than or equal to

• Less than
