Question
What is the graphical representation of the following equations?
x + 2y = 30 and 2x + 4y = 66
- Intersecting lines
- Parallel lines
- Overlapping lines
- None of the above
Hint:
There are countless possible answers for a system of linear equations. The number that makes every equation in a system of linear equations true is the system's solution. The answers to the two variables in the two equations will be these points' coordinates.
In this question we have asked the graphical representation of the equations: x + 2y = 30 and 2x + 4y = 66
The correct answer is: Parallel lines
The value or values that hold true for each equation in the system constitute the solution to the system of equations. How many solutions there are for a system can be determined from the graphs of its equations.
If the point of intersection is the only location where the two graphs meet when the lines cross, the coordinates of that location provide the answer to the equations involving the two variables.
There are no solutions when the lines are parallel. There are always infinitely many solutions when the two equations graph as the same line.
When the lines are coinciding with each other then there is infinite number of solutions.
Now we have given the equations as:
Comparing it, we get:
So it shows that the lines are parallel lines and have no solution.
So here we were asked the nature of the equations, so we used the concept of linear equations and understood with an example that when two lines are parallel with each other, there is no solution for these pair of equations.
