What is an equation of the line that passes through the points (6,−4) and (−6,2)? Put your answer in fully reduced form

katovenus [111]

Y=mx+b
m=slope
b=yintercept
slope=(y1-y2)/(x1-x2)
(x,y)
x1=6
y1=-4
x2=-6
y2=2

(-4-2)/(6-(-6))=-6/12=-1/2
y=-1/2x+b
subsitute one point
(6,-4)
x=6
y=-4
-4=1/2(6)+b
-4=3+b
subtract 3
-7=b
y=-1/2x-7 is answer

Answer:

A. The option that results in the smaller finance charge/interest is option 1

B. The option that will result in the smaller monthly payment is option 1

C. The interest they will earn in 4 years, I = $6,643.972

D. The time it will take for them to earn an interest of $500 by loaning $5,600 at 1.5% is approximately 5.95 years

Step-by-step explanation:

A. The simple interest, I, formula is given as follows;

$I = \dfrac{P \times R \times T }{100}$

Where;

P = The principal

R = The rate

T =The time given for the loan

For Option 1 the first option, we have;

Down payment = 0.2 × $5600.00 = $1,120.00

Principal = $5600.00 - $1,120.00 = $4,480.00

$\therefore I = \dfrac{\$ 4480\times 5 \times 3 }{100} = \$672$

For Option 2. the second option, we have;

P = $5600.00

$\therefore I = \dfrac{\$ 5600 \times 5.25 \times 3 }{100} = \$1176$

The option that results in the smaller finance charge is option 1

B. For option 1, the total amount = Principal + Interest

∴ The total amount remaining = $4480 + $672 = $5,152

The monthly payment = A/N

Where;

A = The total amount yet to be paid out of the loan = $5,152

N = The number of time periods = 3 × 12 = 36 months

The monthly payment = $5,152/36 = $\$ 143.\overline{111}$

For option 2, the total amount = Principal + Interest

∴ The total amount remaining = $5,600 + $1176 = $6776

The monthly payment = A/N

Where;

A = The total amount yet to be paid out of the loan = $6,776

N = The number of time periods = 3 × 12 = 36 months

The monthly payment = $6,776/36 = $\$ 188.\overline{222}$

Therefore, the option that will result in the smaller monthly payment is option 1

C. For a compound interest on a principal of $5,600 invested for 4 years in a savings account that gives an interest rate 21.6% per annum, we have;

$A = P \times \left(1 + \dfrac{r}{n} \right)^{(n\times t)}$

We have, using the annual rate, rather than calculating for the monthly rate;

$A = 5600 \times \left(1 + 0.216 \right)^{4} \approx 12243.972$

Therefore, the amount they will have in 4 years ≈ $ 12,243.972

The interest they will earn in 4 years, I = A - P ≈ $ 12,243.972 - $5,600 = $6,643.972

The interest they will earn in 4 years, I = $6,643.972

D. To earn an interest of $500 at an interest rate of 1.5%, we have;

$500 = \dfrac{5600 \times 1.5 \times T}{100} = 84 \times T$

From which we have;

$T = \dfrac{500}{84} = \dfrac{125}{21} = 5\frac{20}{21} \approx 5.95$

Therefore, the time it will take for them to earn an interest of $500 by loaning $5,600 at 1.5% is approximately 5.95 years.
