Answer:
Many real life situations such as budgeting, finding the rate, making predictions, finding the cost, and the like, can be modelled using linear equations. A linear equation in two variables is an equation that has two variables. You can use any variable other than x and y provide that no more than one variable in each term. The exponent of the variable in each term is one, hence it is an equation for degree 1. If you can see a variable in the denominator or inside the radical sign, then it is a linear equation im two variables. This can be written in the form Ax + By = C which is the standard form. The coefficients of the variables x and y are A and B, respectively, and the constant is C. You can find an ordered pair that satisfies a linear equations in two variables by assigning values of x or y and then by substituting it to the equation to find the value of the other variable. There are many possible set of ordered pairs that satisfy a linear equation in two variables.
