Question

1. Choose correct alternative for each of the following questions
1) To draw graph of 3x+6y= 12, Find y when x = 8
А) 4
В) 3
C) -2
D) -3​

Answer 1

is given

3x+2y=6

We can also write it as

2y=6−3x

y=

2

6−3x

Substituting x=2 in the given equation

y=

2

6−3(2)

So we get

y=

2

6−6

y=0

Substituting X=4 in the given equation

y=

2

6−3(4)

So we get

Y=

2

6−3(4)

So we get

y=

2

6−12

correct options 3

y=

2

−6

By division

y=−3

x: 2 4

y: 0 -3
