Answer:

A mathematical statement where one expression is not equal to another expression is called an

1.

The usual symbols of inequality are > (greater than), <12

J. Siis less than or equal to), and is not equal to). On the other hand, = (equal) is

the symbol used for linear equations in two variables. A Linear 4.

in two variables

can be written in one of the following forms:

Ax & By - C

Ax & BY SC

Ax + By > C

Ах + By 2 с

Both linear equations and linear inequality in two variables can also be presented through graph. The

graph of linear inequality is a 5.

or a 6.

On the other hand,

the graph of a linear equation is a 7.

When a linear 8.

in two variables is multiplied or divided by a negative integer,

the equality symbol does not change. However, when a linear inequality in two variables is 9.

or 10

by a negative integer, the direction of the inequality symbol changes
