The inequality represents all values of x that are greater than or equal to -2 and less than 4. On a number line, this is shown with a closed circle at -2 and an open circle at 4, with a line connecting the two.

To graph the inequality, place a closed circle on -2 (indicating -2 is included) and an open circle on 4 (indicating 4 is not included). Shade the region between -2 and 4.

What is the significance of the slope in a linear equation?

Back

The slope indicates the steepness of the line and the direction it goes. A positive slope means the line rises, while a negative slope means it falls.
