Solve the following inequalities graphically in two-dimensional plane:

$x>-3$

Class 11 | Exercise 6.2 | Linear Inequalities | Maths | NCERT

Solve the following inequalities graphically in two-dimensional plane:

$x>-3$

Solution:

The given inequality is

$x>-3$

Let us draw a dotted line

$x=-3$

in the graph (∵

$x=-3$

is excluded in the given question)

Let us Consider

$x>-3$

A point

$(0,0)$

is selected,

⇒

$0>-3$

⇒

$0>-3$

(this is true)

Therefore, the solution region of

$x>-3$

is right to the line

$x>-3$

. (That is origin is included in the region)

The graph is represented as:

i
