Find the equation of line passing through (-7,-9) and parallel to the 8x-9y+2=0

Lets get started :)

8x - 9y + 2 = 0
9y = 8x + 2
y = 

Since the equation of this line is parallel to the one to be found, both have the same slopes: 

Coordinates : ( - 7 , - 9 )

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

y = 

  3.62 units

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relation between the side adjacent to the angle and the hypotenuse:

  Cos = Adjacent/Hypotenuse

  cos(34°) = AB/AC

  AC = AB/cos(34°) = 3/cos(34°) ≈ 3.619 ≈ 3.62 . . . units

For right triangle ABC with A an angle of 34°, AB of length 3, and AC the hypotenuse.
