Question

If (-3,-4) are the solution of the equation 2x-ay=6,then value of a is:​

Answer 1

Answer:

Given equation is: 2y=ax−4.

It is also given that the point (1,2) lies on the graph of the equation.

⇒2(2)=a(1)−4

⇒a=4+4

⇒a=8

Now, the linear equation is: 2y=8x−4 or y=4x−2

Again, when y=0,x=

1

and

when x=0,y=−2

Therefore, the graph of the equation is as:
