Question

solve the following equations by graphical method

x + y = 1 ; 2x + 3y = 0.

Answer 1

Answer:

Step-by-step explanation:

X+Y=1

If x=1,

1+y=1

Y=1-1=0

If x=2

2+y+1

Y=-1

2x+3y=0

If x=3

2(3)+3y =0

6+3y=0

3y=-6

Y=-2

If x=6

2(6)+3y=0

12+3y=0

3y=-12

Y=-4.

It has unique solution

The lines will intersect each other
