Answer:

-\frac{4}{3}

Step-by-step explanation:

To find the slope of a straight line only two known points on the straight line are sufficient.

If we take the first two points i.e. (-1,3) and (2,-1), then slope of the straight line will be \frac{3-(-1)}{-1-2} = -\frac{4}{3}  (Answer)

Note: Since we know that if a straight line passes through two points (x1,y1) and (x2,y2), then the slope of the straight line is given by m = \frac{y1-y2}{x1-x2}

Please help!! With step by step
Sever21 [200]

Answer:

R=\$145.12

Step-by-step explanation:

<u>Compound Interest</u>

This is a well-know problem were we want to calculate the regular payment R needed to pay a principal P in n periods with a known rate of interest i.

The present value PV or the principal can be calculated with

P=F_a\cdot R

Solving for R

\displaystyle R=\frac{P}{F_a}

Where Fa is computed by

\displaystyle F_a=\frac{1-(1+i)^{-n}}{i}

We'll use the provided values but we need to convert them first to monthly payments

i=7\%=7/(12\cdot 100)=0.00583

n=3*12=36

\displaystyle F_a=\frac{1-(1+0.00583)^{-36}}{0.00583}

F_a=32.386

Thus, each payment is

\displaystyle R=\frac{4,700}{32.386}=145.12

\boxed{R=\$145.12}
