which equation represents a line that will be perpendicular to the graph of 2x-4y=12

Question

i need help please

Answer 1

2x - 4y = 12

-4y = -2x + 12

y = (1/2)x - 3    The slope of this line is 1/2.  Perpendicular lines have slopes that are negative reciprocals of each other.

So, the slope of a perpendicular line will be -2.

 

y = -2x
