Pair of Linear Equations in Two Variables - Key Points

Linear Equation

An equation which can be put in the form ax + by + c = 0, where a, b and c are real numbers and both a and b are nonzero is called a linear equation in two variables.

The solution of an Equation
Each solution (x, y) of a linear equation in two variables.

ax + by + c = 0, corresponds to a point on the line representing the equation, and vice-versa.


Pair of Linear Equations in Two Variables

The general form for a pair of linear equations in two variables x and y is
a₁x + b₁y + c₁ = 0
and a₂x + b₂y + c₂ = 0


Geometrically they look like the following:

1. When a living plant cell loses water through osmosis there is shrinkage or contraction of the contents of the cell away from the cell wall. This phenomenon is known as plasmolysis
(plasma → fluid; lysis → disintegration, decomposition).


2. Only living cells, and not dead cells, are able to absorb water by osmosis.


3. Cell walls permit the cells of plants, fungi and bacteria to withstand very dilute [hypotonic] external media without shrinkage.
