Writing Inequalities from Graphs in Algebra 1

The video tutorial covers the concept of inequalities using number lines, focusing on boundaries and how to express inequalities in mathematical terms. It provides examples with different boundary values, explaining whether the values are included or excluded and how to write the inequalities correctly.

What is the main focus of the exercise introduced in the video?

• Finding the slope of a line

• Drawing graphs

• Writing inequalities from graphs

• Solving equations

• 4

• 3

• Negative 6

• Negative 3

For the boundary at 4, which inequality represents the values?

• x <= 4

• x >= 4

• x < 4

• x > 4

In the second example, what is the boundary value?

• 3

• Negative 3

• 4

• Negative 6

For the boundary at -3, which inequality represents the values?

• x >= -3

• x < -3

• x <= -3

• x > -3

In the third example, what is the boundary value?

• 4

• Negative 3

• 3

• Negative 6

For the boundary at -6, which inequality represents the values?

• x < -6

• x <= -6

• x > -6

• x >= -6

In the fourth example, what is the boundary value?
