Write in Standard Form y-10=9(x+8)

$y - 10 = 9 (x + 8)$

Step 1

The standard form of a linear equation is $A x + B y = C$ .

Step 2

Simplify the right side.

Simplify $9 (x + 8)$ .

Apply the distributive property.

$y - 10 = 9 x + 9 \cdot 8$

Multiply $9$ by $8$ .

$y - 10 = 9 x + 72$

Step 3

Rewrite the equation.

$9 x + 72 = y - 10$

Step 4

Move all terms containing variables to the left side of the equation.

Subtract $y$ from both sides of the equation.

$9 x + 72 - y = - 10$

Move $72$ .

$9 x - y + 72 = - 10$

Step 5

Move all terms not containing a variable to the right side of the equation.

Subtract $72$ from both sides of the equation.

$9 x - y = - 10 - 72$

Subtract $72$ from $- 10$ .

$9 x - y = - 82$
