1. (0,-4)

2. (0,2)

3. (0,6)

4. (0,-3)

Step-by-step explanation:

(i)6x-3y=12

put x=0

6\times0-3y=12\\0-3y=12\\-3y=12\\y=\frac{12}{-3}\\y=-4

put y=-4 in equation(i)

6x-3y=12\\6x-3(-4)=12\\6x=0\\x=\frac{0}{6}\\x=0\\=(0,-4)

(ii)-x+4y=8

put x=0

0+4y=8\\4y=8\\y=2

put y=2 in equation (i)

-x+4\times2=8\\-x+8=8\\-x=8-8\\-x=0\\(0,2)

(iii)2x+y=6\\

put x=0

2\times0+y=6\\0+y=6\\y=6

put y=6 in equation (i)

2x+y=6\\2x+6=6\\2x=0\\x=0\\(0,6)

(iv)3x+2y=-6\\

put x=0

2y=-6\\y=-3

put y=-3 in equation (i)

3x+2(-3)=-6\\3x-6=-6\\3x=0\\x=0\\=(0,-3)

Coordinates and graph are as follows:

• 6x–3y=12

for x=0 y=-4

for x=2 y=0

• Required coordinates (0,-4)&(2,0)

• -x+4y=8

for x=0 y=2

for x=-8 y=0

• Required coordinates (0,2)&(-8,0)

•2x+y=6

for x=0 y=6

for x=3 y=0

• Required coordinates (0,6)&(3,0)

•3x+2y+6=0

for x=0 y=-3

for x=-2 y=0

• Required coordinates (0,-3)&(-2,0)
