What is a linear equation?

• are the expressions where any two values are compared by the inequality symbols such as, '<', '>', '≤' or '≥'

• a polynomial equation of the first degree that gives a straight line when plotted on a graph.

• an equation containing a single variable of degree 2.

• A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality.

What is Linear Inequality?

• are the expressions where any two values are compared by the inequality symbols such as, '<', '>', '≤' or '≥'

• a polynomial equation of the first degree that gives a straight line when plotted on a graph.

• is an equation of the second degree, meaning it contains at least one term that is squared.

• A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality.
