Graphing Systems of Inequalities

What is the first step in graphing inequalities?

• Rewriting the equation into slope-intercept form

• Determining the y-intercept

• Deciding whether the line is dotted or solid

• Identifying the slope

Which inequality symbol indicates that the line should be solid?

• >

• >

• ≥

• <

When should you shade above the line?

• When the line is dotted

• When the line is solid

• When the inequality is > or ≥

• When the inequality is < or ≤

What form should the equation be in to graph it?

• Point-slope form

• Quadratic form

• Standard form

• Slope-intercept form

What is the slope in the equation y = -x + 2?

• -1

• 2

• 1

• -2

How do you determine the y-intercept of an equation?

• By looking at the coefficient of x

• By looking at the constant term

• By dividing the equation by x

• By subtracting x from both sides

What is the first step in graphing the equation y = 2x - 1?

• Plotting the y-intercept

• Drawing a dotted line

• Identifying the slope

• Shading above the line

How do you plot the slope of 2 on a graph?

• Down 1, right 2

• Up 2, right 1

• Up 1, right 2

• Down 2, right 1

What color is used to shade below the line in the example?

• Red

• Green

• Blue

• Yellow

What is the final step in graphing inequalities?

• Finding a solution in the double-shaded area

• Shading the areas

• Identifying the slope

• Drawing the lines
