Question

How to know whether an equation is a linear equation in one or two variable

Answer 1

Step-by-step explanation:

If a, b, and r are real numbers (and if a and b are not both equal to 0) then ax+by = r is called a linear equation in two variables. (The “two variables” are the x and the y.) The numbers a and b are called the coefficients of the equation ax+by = r.

Answer 2

Step-by-step explanation:

if there is 1 variable it is a one variable linear equation.

If there is 2 variables then it is known as 2 variables linear equation
