Question

3.An equation of the form ax + by + c = 0 will be a linear equation in two variables, when a # 0, b 0. Is it True or False

Answer 1

Answer:

ax+by+c=0 represents a linear equation in two variables if and only if a≠0 and b≠ 0 ; c may or may not be zero.

Answer 2

Answer:

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. ... Thus, every solution of the linear equation can be represented by a unique point on the graph of the equation
