Q. 225.0( 1 Vote )

Find the solution

Answer :

2x - y - 1 = 0


y = 2x – 1


Now we need to plot this equation on graph, for that we will take some points of x and put in the equation to obtain points of y.



x + 2y = 8


2y = 8 - x



Now we need to plot this equation on graph, for that we will take some points of x and put in the equation to obtain points of y.

The point of intersection is (2,3)


The line 2x - y = 1 meets the y - axis at (0, - 1)


The line x + 2y = 8 meets the y - axis at (0,4)
