a.
To find: two ordered pairs that represent the function
a.
Answer to Problem 11CFU
Explanation of Solution
Given information:
Length of first tibia,
Height of first tibia,
Length of second tibia,
Height of second tibia,
Calculation:
The two ordered pair for first and second tibia will be as follows:
Put the values of the tibias to get the ordered pairs as follows:
b.
slope of line through the two points.
b.
Answer to Problem 11CFU
Explanation of Solution
Given information:
Length of first tibia,
Height of first tibia,
Length of second tibia,
Height of second tibia,
The ordered pairs is
Calculation:
The slope formula is as follows:
Put the values in the slope formula and simplify it as shown below.
Thus, the slope value is
c.
To explain: the meaning of slope in this context.
c.
Answer to Problem 11CFU
The slope for this linear line equation is positive. As the length of tibia person increases, their height also increases. The increase in height of a tibia is
Explanation of Solution
Given information:
Length of first tibia,
Height of first tibia,
Length of second tibia,
Height of second tibia,
Calculation:
The ordered pairs is
Slope of these two point, m =
The slope intercept formula is as follows:
The above formula can be rewritten after ignoring b as follows:
Here height is y, tibia is x and slope is
The slope for this linear line equation is positive, as the length of tibia person increases, their height also increases. If their height increases by three, their length increases by 8. The increase in height of a tibia is
So, for 1 cm growth of tibia, their height becomes
