Question

if the line represent by the equation 3x+ayequal to 8 passes through the point(2,2) then find the value of a

Answer 1

3x+ay=8
Since it passes through point (2,2),
Hence, (3*2)+(a*2)=8
Or, 6+2a=8
Or, 2a=8-6
Or, 2a=2
Or, a=2/2
Or, a=1 ( Devil's Answer)

Answer 2

Answer:

a=1

Step-by-step explanation:

As we say (coordinates) 2,2

which we know,

x=2  (Given)

y=2  (Given)

In the eq

3x + ay =8  

Putting the values

=> 3*2 + a*2 = 8

=>  6+ 2a = 8

=>  2a= 8-6

=>  a= 2/2

=> a=1

Hope this Helps you
