Important Terms for Pair of Linear Equations
The graph of a pair of linear equations in two variables is represented by two lines.
- If the lines intersect at a point, the pair of equations is consistent. The point of intersection gives the unique solution of the equations.
- If the lines are parallel, then there is no solution the pair of linear equations is inconsistent.
- If the lines coincide, then there are infinitely many solutions. The pair of linear equations is consistent. Each point on the line is a solution of both the equations.
Important Questions on Linear Equations for Practice
- If x = 3m –1 and y = 4 is a solution of the equation x + y = 6, then find the value of m. [Answer: m=1]
- What is the point of intersection of the line represented by 3x – 2y = 6 and the y-axis. [Answer: (0, -3)]
- In a deer park, the number of heads and number of legs of deer and human visitors were counted and it was found that there were 39 heads and 132 legs. Find the number of deer and human visitors in the park. [Answer: Dear: 27, Visitors: 12]
- For what value of p, system of equations 2x + py = 8 and x + y = 6 have no solution. [Answer: p=2]
- From Delhi station if we buy 2 tickets to station A and 3 tickets to station B, the total cost is ₹77, but if we buy 3 tickets to station A and 5 tickets to station B, the total cost is ₹124. What are fares from Delhi to station A and to station B? [Answer: ₹13, ₹17]
- A motor cyclist is moving along the line x – y = 2 and another motor cyclist is moving along the line x – y = 4 find out their moving direction. [Answer: move parallel]
- A farmer sold a calf and a cow for ₹760, thereby, making a profit of 25% on the calf and 10% on the cow. By selling them for ₹767.50, he would have realised a profit of 10% on the calf and 25% on the cow. Find the cost of each. [Answer: Cost of cow = ₹350, cost of calf = ₹300]
Important Questions 10th Maths Exercise 3.1
What do you mean by the solution of a linear Equation?
Every solution of the equation is a point on the line representing it.
How many solutions do a linear equation have?
There are infinite number of points on a line. So, a linear equations have infinite number of solutions.
How many solutions do a system of linear equations have?
A system of linear equations may have o solution or one solutions or infinite many solutions. For a parallel lines, there is no solution at all. for an intersecting lines, only one solutions is there but for coincident lines, infinitely many solutions are possible.
How do we check graphically that the system of linear equations have a unique solutions?
If all the lines are intersecting at one point, then we can say that the system of linear equations are consistent and have a unique solution.
