Graphing Inequalities in ACT Practice Test

What is the initial inequality given in the problem?

• x + y < 1

• 1 < x + y < 2

• x + y > 2

• 1 < x - y < 2

How do you rearrange the inequality to solve for y?

• Add x to all parts

• Divide all parts by x

• Subtract x from all parts

• Multiply all parts by x

What does the slope of -1 indicate about the line's direction?

• It is vertical

• It is horizontal

• It falls as it moves right

• It rises as it moves right

What does the y-intercept of 1 signify in the graph?

• The line is parallel to the y-axis

• The line crosses the y-axis at y = 1

• The line has a slope of 1

• The line crosses the x-axis at x = 1

What does the inequality y < -x + 2 represent in the graph?
