A. 7+5 12
------- = --- = -3
-3-1 -4
Slope=-3
y-y^1=m(x-x^1)
y-7=-3(x+3) Point slope form
y-7=-3x-9
+7 +7
-----------------
y=-3x-2 Slope y-intercept form
+3x +3x
-------------
3x+y=-2 Standard form
is comounded yearly formula
rat ie 4.5%
P=47000
solve for when A=63000
divide both sides by 47000
take the ln of both sides
divide both sides by ln(1.045)
using calculator
6.656=t
so after about 6.7 years
