The video tutorial explains how to graph linear inequalities, emphasizing the importance of understanding slope and y-intercept. It covers graphing in slope-intercept form (y=mx+b) and standard form (Ax+By=C), using methods like the intercept method. The tutorial also discusses using test points to determine shading above or below the line, and how inequality symbols affect the graph's line type (solid or dashed).

What is the y-intercept of a line?

• The point where the line crosses the y-axis

• The slope of the line

• The midpoint of the line

• The point where the line crosses the x-axis

In the slope-intercept form y = mx + b, what does 'm' represent?

• The midpoint

• The slope

• The x-intercept

• The y-intercept

How can you find the x-intercept of a line in standard form?

• Use the midpoint formula

• Use the slope-intercept form

• Set x to 0 and solve for y

• Set y to 0 and solve for x

What is the purpose of using test points in graphing linear inequalities?

• To find the slope of the line

• To determine the y-intercept

• To decide where to shade the graph

• To calculate the midpoint

When should a line be drawn as dashed in a graph of a linear inequality?

• When the inequality is equal to

• When the inequality is less than or greater than

• When the inequality is greater than or equal to

• When the inequality is less than or equal to
