First you have to change your equation to slope-intercept form.Make everything equal to y, do y=-(4x/3)+(8/3). Parallel lines means that slope is the same. In this case, your equation will have the slope m=4/3. Then you would plug in your given point into y=(4x/3)x+b, so it would like -2=(4(4)/3)+b. Solve for "b," and plug into this equation: y=(4x/3)+b. That would your final answer.

10%-3%=7%=$3.64
Answer=$3.64
Plug in 40,000 for p(n), then use algebra. First step divide by 18. Then you have 2222.222222=e^0.035n.
Take the natural logarithm (Ln) on your calculator of both sides:
Ln(2222.2222)=Ln(e) 0.035n
Ln2222.2222 just gives you a number and Ln(e) cancel each other so you have:
Ln(2222.222222)= 0.035n, divide both sides by 0.035 and you will find “n”(the number of years after 2000).
The second method is trial and error, keep plugging in numbers for n starting at “1” and see what number gets you closest to 40,000 when you calculate the equation
