y - (- 9) = - 6 (x - (- 7))

$y - (- 9) = - 6 (x - (- 7))$

Step 1

The slope-intercept form is

y = m x + b

$y = m x + b$ , where

m

$m$ is the slope and

b

$b$ is the y-intercept.

y = m x + b

$y = m x + b$

Step 2

Rewrite in slope-intercept form.

Step 2.1.1

Multiply

- 1

$- 1$ by

- 9

$- 9$ .

y + 9 = - 6 (x - (- 7))

$y + 9 = - 6 (x - (- 7))$

y + 9 = - 6 (x - (- 7))

$y + 9 = - 6 (x - (- 7))$

Step 2.2.1.1

Multiply

- 1

$- 1$ by

- 7

$- 7$ .

y + 9 = - 6 (x + 7)

$y + 9 = - 6 (x + 7)$

Step 2.2.1.2

Apply the distributive property.

y + 9 = - 6 x - 6 \cdot 7

$y + 9 = - 6 x - 6 \cdot 7$

Step 2.2.1.3

Multiply

- 6

$- 6$ by

7

$7$ .

y + 9 = - 6 x - 42

$y + 9 = - 6 x - 42$

y + 9 = - 6 x - 42

$y + 9 = - 6 x - 42$

y + 9 = - 6 x - 42

$y + 9 = - 6 x - 42$

Step 2.3

Move all terms not containing

y

$y$ to the right side of the equation.

Step 2.3.1

Subtract

9

$9$ from both sides of the equation.

y = - 6 x - 42 - 9

$y = - 6 x - 42 - 9$

Step 2.3.2

Subtract

9

$9$ from

- 42

$- 42$ .

y = - 6 x - 51

$y = - 6 x - 51$

y = - 6 x - 51

$y = - 6 x - 51$

y = - 6 x - 51

$y = - 6 x - 51$
