Question

solve the following simultaneous equation graphically :- x+y=0 ; 2x-y=9
​

Answer 1

step by step explain

X+y=0 ; 2x-y=9 Solve the simultaneous equation graphically.

We will make graph of above two given lines and find their point of intersection.

To make graph of these lines, we require at least two points on each line. In x + y = 0 , When x = 0, then y = 0. When x = 1 , y = -1. ...

The point of intersection of these lines will give solution of given two simultaneous equations.
