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:
Yes, 1:3.
Step-by-step explanation:
Each of the numbers on figure 2 are 3 times the number on figure 1.
Answer:
Figures A,D are polygons.
Reason:
Polygon is a closed figure with atleast three strange lines and angles.
Answer: the circumference is 25.13 and the area is 50.26 if rounding up then 50.27
Step-by-step explanation: to find circumference it is 2piR and to find the area it is piR^2
