Step-by-step explanation
There are 72 heads (chicken and rabbit) and 200 legs. How many chickens and rabbits are present totally?
Legs of a chicken = 2
Legs of a rabbit = 4
Total heads = 72
Total legs= 200
Let's assume that each of them has minimum 2 legs.
So 72*2 = 144 legs
Remaining legs: 200-144= 56
These remaining legs belong to rabbit because rabbit has 4 legs each.
2*Rabbits= 56
Rabbits= 56/2 = 28
Out of 72, 28 are rabbits. So there are 72-28= 44 chicken.

Answer/Step-by-step explanation:
An equation that describes the relationship can be written as
.
Using the two sets of coordinates, (2, 140) and (4, 280), calculate the slope (m) as shown below:

Substitute m = 70 into 
The equation would be:

This equation can be interpreted as follows:
