Question

2,000 - 61k = 48
In 1962, the population of a bird species was 2,000.
The population k years after 1962 was 48, and k
satisfies the equation above. Which of the following
is the best interpretation of the number 61 in this
context?

Answer 1

Answer:

61 is the rate at which the population changes every year

Step-by-step explanation:

Given

$2000 - 61k = 48$

Required

Interpret 61

A linear equation has the form:

$y = mk + b$

or

$b + mk = y$

Where m is the rate

By comparison:

$mk = -61k$

$m = -61$

Hence, 61 represents the rate at which the population changes yearly.

The negative sign implies that the populatiin reduces
