How to find slope when there is the y intercept and x-intercept?
natta225 [31]
First graph your x and y intercept then pick any two points on the line.
\frac{rise}{run} = \frac{y2 - y1}{x2 - x1}
that's the equation used to find your slope

Example:

(4,2) (8,6) let's say those are the points you pick from the line

so then you subtract 6-2=4 (6 is your y2 and 2 is your y1)

then subtracts 8-4=4 (8is your x2 and 4 is your x1)

then your left with
\frac{2}{4}
if you can reduce the reduce in this case you can which leaves you with
\frac{1}{2}
and that's how you find the slope

What annual rate of interest is required to triple an investment in 7 years if it were compounded quarterly?
Jobisdone [24]

Answer:

Option C) 16.01%

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=7\ years\\P=\$x\\A=\$3x\\n=4  

substitute in the formula above  

3x=x(1+\frac{r}{4})^{4*7}  

3=(1+\frac{r}{4})^{28}  

Apply log both sides

elevated both sides to 1/28

\sqrt[28]{3}=(1+\frac{r}{4})

Multiply by 4 both sides to remove fraction

4\sqrt[28]{3}=4+r

subtract 4 both sides

r=4\sqrt[28]{3}-4

r=0.1601

convert to percentage

r=0.1601*100=16.01\%
