*I'm not exactly sure what it means by compare the percents of change*

From 2000 to 2005, that's 5 years.
After 5 years, the population decreased from 4.3 mil to 3.2 mil; 3.2 - 4.3 = -1.1; that's a decrease of 1.1 mil.
1.1 mil out of 4.3 mil is approximately 26%.
So from 2000 to 2005, the population decreased by 26%.

From 2005 to 2010, that's also 5 years.
After that 5 years, the population increased from 3.2 mil to 5.6 mil; 5.6 - 3.2 = 2.4; that's an increase of 2.4 mil. 2.4 mil out of 3.2 is 75%.
So from 2005 to 2010, the population increased by 75%.

System of equations, special case infinitely many solutions?????
Mashcka [7]

One possible system is

1x + 3y = 4

2x + 6y = 8

Note how 2 is twice as large as 1, 6 is twice as large as 3, and 8 is twice as large as 4.

In other words, the second equation is the result of multiplying both sides of the first equation by 2.

1x+3y = 4

2*(1x+3y) = 2*4

2x+6y = 8

Effectively the two equations in bold are the same which produces the same line. The two lines overlap perfectly to intersect infinitely many times. An intersection is a solution.
