Question

The height and weight of adults can be related by the equation y=48.3x−127 where x is height in feet and y is weight in pounds.

What does the slope of the line represent?
A. the average number of pounds per foot tall
B. the number of pounds heavier an adult one foot taller would weigh
C. the height of an adult weighing zero pounds
D. the number of adults in the sample

Answer 1

we conclude that the correct option is A, the slope is:

"the average number of pounds per foot tall"

What does the slope of the line represent?

The linear equation:

y = 48.3*x - 127

Relates the height, x, and the weight, y of an adult.

Then the slope, which is 48.3, should have units of mass over height.

Now, if x is in feet and y is in pounds, then the slope has units of pounds/feet.

Then it represents the mean number of pounds per feet. So we conclude that the correct option is A:

"the average number of pounds per foot tall"
