We have (x-4)/(-6-4) = (y-4)/(-4-4);
(x-4)/(-10) = (y-4)/(-8);
(x-4)/5 = (y-4)/4;
4x-16 = 5y-20;
4x - 5y + 4 = 0;
PEMDAS
(9)(5) + 8
45 + 8
53
Answer:
The third one
Step-by-step explanation:
Answer:

Step-by-step explanation:
Given f(x)=
We have to find 
In order to find
we have to make x as the subject of the formula
Let us assume f(x)=y
⇒
Subtracting both sides by 5


Dividing both sides by 2

⇒
Now substituting y with x
we have 
Now 
=
So option (ii) is correct
