Answer:
An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero. For example, 10x+4y = 3 and -x+5y = 2 are linear equations in two variables.

Answer:
he numbers a and b are called the coefficients of the equation ax+by = r. The number r is called the constant of the equation ax + by = r. Examples. 10x - 3y = 5 and -2x - 4y = 7 are linear equations in two variables.
