Mathematics 8 Quarterly Exam

Which of the following represents a linear inequality in two variables?

• y=2x+3

• y≥x-5

• 3x+4y=12

• x+y=8

Identify the expression that is a linear equation in two variables.

• x+2y>6

• y≤3x+1

• 4x-y=7

• 2x+3y≥10

What is the main difference between a linear inequality and a linear equation in two variables?

• A linear inequality can have two variables, but a linear equation cannot.

• A linear equation always has a solution, while a linear inequality does not.

• A linear inequality uses symbols like '<' or '>', while a linear equation does not.

• A linear equation represents a straight line, while a linear inequality represents a curved line.
