Write the slope-intercept form of the equation of each line given the slope and y-intercept.

saul85 [17]

Answer:

4b. −6x + y = −4

4a. 7x + 4y = −12

3b. y = ½x + 3

3a. y = −6x + 5

2b. y + 2 = −⅔(x + 3)

2a. y - 3 = ⅘(x - 5)

1b. y = -x + 5

1a. y = 5x - 3

Step-by-step explanation:

Plug the coordinates into the Slope-Intercept Formula first, then convert to Standard Form [Ax + By = C]:

2 = 6[1] + b

−4 = b

y = 6x - 4

-6x - 6x

_________

−6x + y = −4 >> Standard Equation

4 = −7⁄4[-4] + b

−3 = b

y = −7⁄4x - 3

+7⁄4x +7⁄4x

____________

7⁄4x + y = −3 [We do not want fractions in our Standard Equation, so multiply by the denominator to get rid of it.]

4[7⁄4x + y = −3]

7x + 4y = −12 >> Standard Equation

__________________________________________________________

Plug both coordinates into the Slope-Intercept Formula:

5 = ½[4] + b

3 = b

y = ½x + 3 >> EXACT SAME EQUATION

−1 = −6[1] + b

−6

5 = b

y = −6x + 5

* Parallel lines have SIMILAR RATE OF CHANGES [SLOPES].

__________________________________________________________

b. y + 2 = −⅔(x + 3)

a. y - 3 = ⅘(x - 5)

According to the Point-Slope Formula, y - y₁ = m(x - x₁), all the negative symbols give the OPPOSITE TERMS OF WHAT THEY REALLY ARE, so be EXTREMELY CAREFUL inserting the coordinates into the formula with their CORRECT SIGNS.

__________________________________________________________

b. y = -x + 5

a. y = 5x - 3

Just write out the Slope-Intercept Formula as it is given to you.

I am joyous to assist you anytime.

Use Lagrange multipliers to solve the following exercise. A home improvement contractor is painting the walls and ceiling of a r

mash [69]

Answer:

Let the width of the garden =x meter

Then length=(x+4) meter

Half perimeter =36 m

So perimeter of garden =(2×36)=72 meters

According to the question

⇒2(l+b)=72

⇒2(x+x+4)=72

⇒2x+2x+4=74⇒4x=64⇒x=16 meters

Hence,the width of the garden =16 meters

The length of the garden =(16+4)=20 meters

To solve -9 - 16m = 7, what steps would you use?

zlopas [31]

Answer:

M=-1

Step-by-step explanation:

To solve -9-16m=7 need to us Inverse operations.

What is inverse operation?

Inverse operation is an operation subtraction, addition, division, or multiplication that undo's the given operation.

As showed as the image below.

so our goal is to isolate the variable.

A variable is a symbol in math a variable is some type of Letter in the alphabet.

Isolate the variable means (shown in the image below)

so first what we need to move is a number.

-16 is being multiplied by m

so easiest number to move at this point is -9 its being subtracted so we need to add 9 on both sides to move it.

after this we need to move -16m to move it we need to divide by -16

At this point m will be on one side.

and we need to simplify the left side.

these steps are shown in the image below once you are done

M will equal something.

once we simplify we get

m=-1

we want to plug it in to see if we are correct

as show in my steps in the image.
