The number of additional tea bags that are needed to make each additional cup of tea is: B. one.
What is a linear function?
A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.
What is a slope?
A slope is also referred to as gradient and it's typically used to describe both the ratio, direction and steepness of the function of a straight line.
Mathematically, the standard form of the equation of a straight line is given by;
y = mx + c
Where:
- m is the slope or rate of change.
Comparing the given equation with the standard form of the equation of a linear function, we have:
t ⇒ y, n ⇒ x;
t = n + 2 ≡ y = mx + c
Therefore, we can logically deduce that the slope (m) is equal to one (1).
