how can we find out the graph of pair if linear equations in two variables
Answers
Answer:
We can easily find it out.
Just take any one of the equation and find it's solution but taking different values of x or y and the finding the value of correspondent variable. After taking minimum three such different pairs of values plot them on the graph and join the points. You will always get a straight line for linear equation.
Now, take another equation and repeat the same steps as taken for 1st equation. You will get two lines of graph from which you can find the solution of the equations if it exists.
Step-by-step explanation:
Answer:
First you should have two linear equations.
Find the coordinates through substitution method.
Plot the coordinates of first equation first.
Then draw a line through that points.
In the same way do for second equation.
If the lines intersect at any point it is called consistent.
Sometimes it may coincide.
