Hi

 



1.what is the equation of line passes through points (4,-6) and has a slope of -3 

  y = -3x + b   |using ordered pair pt( 4,-6) to solve for b

 -6 = -12

 6 = b   | y = -3x+6  OR 3x+y = 6



2.what equation represent a line parallel to the graph of 2x-4y=16

 2x-4y=16  OR y = (1/2)x - 4   |these 'parallel' lines would have m = (1/2)

New Line

  y = (1/2)x + b  | b can be any real value for this line
