Equation of a straight line Show
- A linear equation is an equation, when graphed, produces a straight line.
- For example:
- More generally, it is any equation of the form:
- a1 to an and b are real numbers, and are the coefficients of the equation.
- x1 to xn are the variables of the equation.
- Linear equations do not contain terms such as:
- Because these terms are not linear
- they do not produce straight lines when graphed.
