(-4, -7) and (-6, 9) in slope-intercept form. Show work
BigorU [14]

Answer:

Equation of line in slope-intercept form is: y = -8x-39

Step-by-step explanation:

Given points are:

(-4, -7) and (-6, 9)

The slope-intercept form is given by the equation

y = mx+b

Here m is the slope of the line and b is the y-intercept.

m is found using the formula

m = \frac{y_2-y_1}{x_2-x_1}

Here

(x1,y1) = (-4-7)

(x2,y2) = (-6,9)

Putting the values in the formula

m = \frac{9+7}{-6+4} = \frac{16}{-2} = -8

Putting slope in general equation

y = -8x+b

Putting (-6,9) in the equation

9 = -8(-6)+b\\9 = 48+b\\b = 9-48\\b = -39

Putting the value of b we get

y = -8x-39

Hence,

Equation of line in slope-intercept form is: y = -8x-39

Ami'yan runs every day for exercise at a rate of 1 kilometer every 15 minutes. How many meters does he run in 1 hour? - Thank yo
Alona [7]

Answer:

The total distance covered in 1 hour  is 4000 meters.

Step-by-step explanation:

The distance Ami'yan runs is 15 minutes = 1 kilometer

Using the unit formula,

The distance ran in 1 minute = (\frac{1}{15} ) \textrm{Kilometer}

Now, 1 hour = 60 minutes

⇒The distance covered in 60 minutes =  60 x (Distance run in 1 minute)

                                                               = 60 \times \frac{1}{15}    = 4

So, the distance covered in 1 hour  = 4 kilometer

1 kilometer = 1000 meters

⇒ 4 km =  4 x 1000 meters = 4000 m

Hence, the total distance covered in 1 hour  = 4000 meters.

You and your friend are comparing two loan options for a $165,000 house. Loan 1 is a 15-year loan with an annual interest rate o
Harlamova29_29 [7]

Answer:

No, he is wrong.

Step-by-step explanation:

Since, the total payment of a loan after t years,

A=P(1+r)^t

Where,

P = present value of the loan,

r = rate per period ,

n = number of periods,

Given,

P = $165,000,

In loan 1 :

r = 3% = 0.03, t = 15 years,

So, the total payment of the loan is,

A_1 = 165000(1+0.03)^{15}=165000(1.03)^{15}\approx \$ 257,064.62

In loan 2 :

r = 4% = 0.04, t = 30 years,

So, the total payment of the loan is,

A_2 = 165000(1+0.04)^{30}=165000(1.04)^{30}\approx \$ 535,160.59

Since, A_1 < A_2

Hence, total amount repaid over the loan will be less for Loan 1.

That is, the friend is wrong.

Distinguish differences and similarities between slope intercept form and point slope form ohysics
Slav-nsk [51]

Differences:

point slope form of line:

(a) equation is (y-y_1)=m(x-x_1)

where m is slope and (x1,y1) is a point

(b)This equation of line can be determined when two points are given

(x1, y1) and (x2,y2)

slope intercept form of line:

(a) equation is y=mx+b

where m is a slope

b is y-intercept

(b)This equation of line can be determined when y-intercept and slope are given

Similarilties:

(a) both are equation of straight line

(b) slope is always constant in both
