Review Inequalities and graphing slope Intercept

Front

What does the inequality x ≥ -5 mean?

Back

The value of x is greater than or equal to -5.

Front

When graphing the inequality x < 3, what type of circle is used?

Back

An open circle is used to indicate that 3 is not included.

Front

Which inequality is represented by the graph that shows all values less than 3?

Back

k < 3.

Front

What is the slope-intercept form of a line?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you determine if a point lies above or below a line in a graph?

Back

If the y-value of the point is greater than the y-value of the line at the same x-value, it lies above; otherwise, it lies below.

Front

What does the inequality a ≥ 11 indicate about the value of a?

Back

The value of a is greater than or equal to 11.

Front

What is the difference between a closed circle and an open circle on a number line?

Back

A closed circle indicates that the number is included in the solution (≥ or ≤), while an open circle indicates it is not included (> or <).

Front

How do you graph the inequality y < 2x + 1?

Back

Graph the line y = 2x + 1 with a dashed line and shade below the line.

Front

What is the slope of the line represented by the equation y = -3x + 2?

Back

The slope is -3.

Front

If a line has a positive slope, what does that indicate about the relationship between x and y?

Back

As x increases, y also increases.
