Which of the following equations represents a line that is perpendicular to y=1/4*x+2? Choose the correct choice from the following choices.
A) y−2x=8 B) 2x+4y=10 C) 3y+6x=12 D) 4y−8x=16 E) 5x−10y=20
For two lines to be perpendicular, the product of slopes should be equal to -1.   Slope of line 1 = 1/2   Slope of the line perpendicular to line 1 must be -2. Option C can be rewritten as y = -2x + 4 --&gt; Slope = -2   Answer: 4y−8x=16
