Question

y=2x-2,y=4x-4 find the graph​

Answer 1

Step-by-step explanation:

ANSWER

2x−y=2 ----- (1)

2x−y=2 ----- (1)−4x−y=−4 ----- (2)

From equation (1)

From equation (1)y=2x−2 ------ (3)

Assume the value of x = 1, 2 and put those values in equation (3)

Assume the value of x = 1, 2 and put those values in equation (3)If x=1,y=2(1)−2=0

Assume the value of x = 1, 2 and put those values in equation (3)If x=1,y=2(1)−2=0If x=2,y=2(2)−2=2

On the above basis, the following points are:

On the above basis, the following points are:X 1 2

On the above basis, the following points are:X 1 2Y 0 2

Now plotting (1, 0), (2, 2) and joining them, we get a straight line.

From equation (2),

From equation (2),−4x−y=−4

From equation (2),−4x−y=−4y=−4x+4 ------ (4)

Assume the value of x=1,2 and put those values in equation (3)

Assume the value of x=1,2 and put those values in equation (3)If x=1,y=−4(1)+4=0

Assume the value of x=1,2 and put those values in equation (3)If x=1,y=−4(1)+4=0If x=2,y=−4(1)+4=−2

Now table the following points:

Now table the following points:X 1 2

Now table the following points:X 1 2Y 0 -2

Plotting (1, 0), (2, -2) and joining them, we get another straight line.

These lines intersect at the point (1, 0) and therefore the solution of the equation is x=1,y=0 (see fig.)

These lines intersect at the point (1, 0) and therefore the solution of the equation is x=1,y=0 (see fig.)solution.
