**1. What is a linear equation?**

An equation that shows the relation between two variables with power 1 is called a linear equation.

**2. What happens when we plot a linear equation in a coordinate graph?**

When we plot a graph using the values of two variables of a linear equation, we get a straight line. Every coordinate point in this line complies with the linear equation.

**3. What is the substitution method?**

When one variable in a linear equation is eliminated by using another variable, it is called the substitution method.

**4. What is the elimination method?**

When the coefficient of a variable in linear equations is adjusted to eliminate the variable, it is called the elimination method.

**5. What is the constant of a linear equation?**

The part of a linear equation with no variable is called a constant.
