Ineed to convert the slope intercept form to standard form

Standard Form is: Ax + By = C  ; where A, B, and C are integers and A is positive

7y = -3x - 23              Multiply both sides by 7

3x + 7y = -23             Add 3x to both sides

3x + 7y = -23

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

to complete this square you have to rotate about the origin 270 degrees clockwise.
