This is an example of an exponential decay problem.
The basic format of the equation is:

In this problem, the starting amount is 100. The rate is 0.5 because it is being cut in half every 330 days.
It would x - 4 = y because tge opposite reciprocal of -1 is 1 and so using point slope form y + 2 = x - 2 and when simplified youll get x - 4 = y.
Answer:
Step-by-step explanation:
Equation of the line y = mx + c
The new line is perpendicular to 2x - 3y = -5
- 3y = - 5 - 2x
3y = 2x + 5
y =
Since the lines are perpendicular to each other : 
where
.
Slope of the given line

Slope of the new line

The equation to the new line passing through (-4, -3) and perpendicular to 2x - 3y = -5
