You can graph a solution to an equation or an inequality on a number line.
Equation: 5=x
Inequality:X>4
Title: Nov 21­1:46 PM (2 of 11)
A solution for an equation requires a point (a solid dot)
The arrow represents
a set of values that are all solutions.
A solid circle states that the solution is that value.
A solution for an inequality requires a point
(solid or open) and an arrow.
­1
X=-1
A solid circle states
that the solution set
will include that value.
0
An open circle states
X>-1
that the solution set
will not
include that va

To graph a solution to an equation,
place a point (a solid circle) on the correct value,
on the number line.
To graph a solution set for an inequality, choose the correct circle
for the inequality symbol used and then place the arrow the
direction of the solution set.
