Answer:
Step-by-step explanation:
We are to write a linear equation that relates y in terms of x
The Birth Rate in 1994 = 14.6 births per thousand population.
The Birth Rate in 2004 = 14.32 births per thousand population.
A linear equation is of the form y=mx+b, where:
- x=Number of Years after 1994
- y=the birth rate
- m=Birth rate per year
Step 1: Determine the birth rate per year
In 1994, x=0, y=14.6 thousands
In 2004, x=10, y=14.32 thousands
Substituting m into our linear equation, we have:
When x=10, y=14.32
Therefore, a linear equation that relates y in terms of x is:
