Convert to the form y = a/(x -h) + k

• y = 4 + 7/(x + 2)

• y = -4 + 7/(x + 2)

• y = 7 + 4/(x + 2)

• x + 2 - 4

Multiply and Simplify

• 4(x+3)/(x+2),

• (x+2)/4(x+1)

• (x+2)/4(x+3),

• 4(x+1)/(x+2),

Perform the operation

• A
• B
• C
• D

Divide

• 1/6

• x+10/ 6x+60

• x+8/ 6x+60

• (x+10)(x+8)/ 6x+60
