Question

if the graph of the equation 2y=ax-4 passes through the point (1,2 ) then find the value of a.​

Answer 1

Step-by-step explanation:

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=
