Find the equation of a line that passes through (5,-3) and is perpendicular to y = x.
VashaNatasha [74]
We know the slope is -1, because perpendicular line's slopes are always the negative reciprocal. We plug (5, -3) in to get:
-3 = -5 + b
b = 2
So we get C. y = -x + 2.

If we assume that 2010 is t=0 what is the initial value and what does it mean?
timurjin [86]

The initial value is 309.35

It means that in the year 2010 (starting year) the population was 309,350,000 people or written another way "309.35 million". The second way is more short so probably the more preferred method.

To find the value 309.35, simply look at the table under the value t = 0.
