The systems in those three examples had at least one solution. The given equations will represent coincident lines if they have infinitely many solutions. It cannot be no solutions because in order for that to happen the line would have to be parallel, and if the lines intersect that means they cannot be parallel (the very definition of a parallel line being that they do not touch.) column A vertical line of objects in a rectangular array. What is the Difference Between Blended Learning & Distance Learning? If then the pair of linear equations has exactly one solution. All Rights Reserved.

It could theoretically be infinite, but in order for that to happen they would have to be the same line. In math, lines that are 'hiding' have a special name! Log in or sign up to add this lesson to a Custom Course. Then you have one equation with one variable and you can solve for that variable. Don't worry, remember that lines go in both directions forever. In Algebra, we have learned that a line can be represented with an equation. Create your account, Already registered? ; If then the pair of linear equations has no solution. A system of equations that has at least one solution is called a consistent system. © copyright 2003-2021 Study.com. One line might lie on top of another line so that you can't tell it is even there. Two lines that coincide have how many solutions or points in common. If you make those lines keep going, they will cross at right angles. the equation you will be able to determine what type of lines they are. 1. Question 2.

One line is on top of the other, you just can't tell. If each line in the system has the same slope and the same y-intercept, the lines are coincident. Solution to example problem 1 (c)—an Inconsistent pair of linear equations in two variables. 's' : ''}}. The equation will represent coincident lines only when they have infinite number of solutions. There are oblique lines, lines that cross that are not parallel or perpendicular, and there are coincident lines. Choose a variable to eliminate. Coincident lines Example They have an infinite number of solutions.
