The line passes through the point (-2,-5) and has a slope of -3.
JulsSmile [24]

Answer:

y = - 3x  -11

Step-by-step explanation:

(x₁ , y₁) = (-2 , -5)   & m = -3

y - y₁ = m (x - x₁)

y - [-5] = (-3)(x -[-2])

y + 5   = (-3)(x + 2)

y + 5  = -3x - 6

      y = -3x - 6 - 5

      y = - 3x  -11

Solve for x: 81 ^-2 : 729 ^1-X = 9 ^2x​
34kurt

Answer:

x=0

Step-by-step explanation:

(1): "^-2" was replaced by "^(-2)".

rearrange the equation: x/81^(-2)/729^1-x-(9^2*x)=0

STEP

1

:

1.1 9 = 32

(9)2 = (32)2 = 34

Equation at the end of step

1

:

x

(—————— ÷ (7291)-x)-(34•x) = 0

(81-2)

STEP

2

:

2.1 729 = 36

(729)1 = (36)1 = 36

Equation at the end of step

2

:

x

(—————— ÷ 36 - x) - 34x = 0

(81-2)

STEP

3

:

3.1 81 = 34

(81)-2 = (34)(-2) = (3)(-8)

Equation at the end of step

3

:

x

(——————— ÷ 36 - x) - 34x = 0

(3)(-8)

STEP

4

:

1

Divide x by ——

38

Equation at the end of step

4

:

38x

(——— - x) - 34x = 0

36

STEP

5

:

38x

Simplify ———

36

Dividing exponents:

5.1 38 divided by 36 = 3(8 - 6) = 32

Equation at the end of step

5

:

(9x - x) - 34x = 0

STEP

6

:

Equation at the end of step 6

-73x = 0

STEP

7

:

Solving a Single Variable Equation:

7.1 Solve : -73x = 0

Multiply both sides of the equation by (-1) : 73x = 0

Divide both sides of the equation by 73:

x = 0

One solution was found :

x=0

What is the equation of the line that passes through the point (-6, -2) and has a<br> slope of 1/6
Levart [38]
<h2>Answer:</h2>

Step 1: Determine <u><em>b</em></u> by using the point (-6,-2), the given slope, and the slope intercept formula, y = mx + b.

y = mx + b\\\\-2 = \frac{1}{6}(-6) + b\\\\-2 = -1 + b\\\\-1 = b

Step 2: Now that we have <u><em>b</em></u>, we can determine the equation of the line.

y = \frac{1}{6}x -1

I didn't use <em>+ (-1)</em> because <em>b</em> is negative. Therefore you need to change the equation from <em>y = 1/6x + (-1)</em> to <em>y = 1/6x - 1</em>.
