Question

Draw the graph of the linear equation
2x + 3y = 12
(i) Write the co-ordinates of a point where
graph intersects x-axis.
(ii) From the graph show whether points (3, 2)
and (–3, 6) are the solution of the equation.

Answer 1

Answer:

Put x=0 you will get a point on line

Put y=0 you will get an another point on graph...

i) for x-axis, y=0, so you will get x and (x,0) will be your point on x axis...

ii) just puts the points in the equation,

For (3,2), put x =3 and y=2 if LHS =RHS then the point is on line....

Answer 2

Answer:

1) (6,0)

2) yes

Step-by-step explanation:

1)2x=12-3y

x=12-3y/2

if y=0 then x=12-3(0)/2

x=12/2

x=6

(6,0)

2)y=2 ~x=12-6/2

x=3

y=6~x=12-18/2

x=-6/2

x=-3
