Answer:
Option C is correct.
The equation
represents the function.
Step-by-step explanation:
Using slope intercept form to find the equation of line :
For any two points
and
the equation of line is given by:
......[1] ;where m is the slope given by:

Consider any two points from table :
let (4, 2) and (0, 4) be any two points.
calculate slope:


Now, substitute in equation [1] we have:

Distributive property i.e, 

Add both sides 2 we get;

Simplify:

Since, y= f(x)

therefore, the equation
represents the function.
Answer:
I think it's C because it's the only one that is different. I could be wrong though

Answer:
Step-by-step explanation:
<u>Direct variation equation:</u>
- y = kx, where k is constant of variation
<u>Given:</u>
<u>The equation is:</u>
<u>Find the value of x when y = 168:</u>
- 168 = 12x
- x = 168/12
- x = 14
