Answers
Answer:
Step-by-step explanation:
An equation is a statement in which one expression equals to another expression. An
equation of the form ax + by + c = 0, where a, b and c are real numbers such that
a ≠ 0 and b ≠ 0, is called a linear equation in two variables. The process of finding
solution(s) is called solving an equation.
The solution of a linear equation is not affected when
(i) the same number is added to (subtracted from) both sides of the equation,
(ii) both sides of the equation are multiplied or divided by the same non-zero
number.
Further, a linear equation in two variables has infinitely many solutions. The graph of
every linear equation in two variables is a straight line and every point on the graph
(straight line) represents a solution of the linear equation. Thus, every solution of the
linear equation can be represented by a unique point on the graph of the equation. The
graphs of x = a and y = a are lines parallel to the y-axis and x-axis, respectively.
