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.
