For this case we have that by definition, having two points through which a line passes , we can find its slope of the following form:
If we have:
We know that equal signs are added and the same sign is placed
So, the slope of that line is
Answer:
Given:
The length of field is n yards.
The length of a field in feet is a function f(n).
To find:
The function rule for this situation.
Solution:
We know that,
1 yard = 3 feet
Using this conversion, we get
n yard = 3n feet
The length of field is n yards. So, the length of the field is 3n feets.
The length of a field in feet is a function f(n). So,
Therefore, the required function rule for this situation is .
