First off, you have to find a common denominator between 6 and 9 which is 18, so to rewrite your equation using the common denominators it would be 15/18+(-8/18)-(-36/18) when you combine these it equals (7/18)-(-36/18)=43/18
The slope 3 is and the y-intercept is 6.
As it has been given that
,
.
We need to find the value of the following:
(i)
, substituting the value of 'x' and 'y' in the expression, we get:


So, 
(ii)
, substituting the value of 'x' and 'y' in the expression, we get:


So, 
(iii)
, we need to substitute the value of 'x' and 'y' in the expression, for this, we can use distributive property of multiplication that says,

Using the distributive property of multiplication:


Now, we know that 
We get, 

Therefore,
=
.
(iv) We have,
, we need to substitute the value of 'x' and 'y' in the expression, we get:

Again, we can use distributive property of multiplication that says,

So,



since, 
we get,


Therefore,

Answer: multiplication i think
