Check graphically whether the pair of equations constituent. X+3y=6 2x-3y=12
  • 3 answers

The given equations is 

x+3y=6.......(i)

 

2x-3y=12....(ii)

 

Now, from equation (i)

If x= 0, then 

0+3y=6

3y=6

y=6/3

y=2

 

(x,y) =(0,2)...(I)

and when y=0 , then 

x+0=6

x=6

 

(x,y) =(6,0)........(II)

 

Now,

from equation (ii),

If x= 0, then 

0-3y=12

y=-4

(x,y)=(0,-4)...............(III)

and 

if y=0

2x-0=12

x=6

(x,y) = (6,0)............(IV)

 

Mark these points (I), (II) , (III) & (IV) on graph as shown below:

 

thus,  x + 3y = 6 intersects y–axis at (0, 2) and 

 2x – 3y = 12 intersects y–axis at (0, – 4).
