Question

Which inequality corresponds with the graph?

A) x > -2

B) x < -2

C) x ≤ -2

D) x ≥ -2

Answer 1

D

Explanation:

An inequality is an expression which means more than one number is a solution. We graph the solutions on a number line to show all possible values. We graph using circles and arrows.

• Equal to and less/greater than are graphed with filled in circles on the value.
• Only less/greater than (not equal to) are graphed with open (not filled in) circles on the value.
• We draw an arrow the direction the solutions satisfy the inequality. Generally this is the direction the inequality itself points.

This is a filled in circle on -2 so this is
`\leq or \geq`. This means only answers C and D are options.

Answer D points to the right.
