Which of the following equations represents a line that is perpendicular to y=1/2*x+1?
Choose the correct choice from the following answers
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   y−2x=8nswer: y−2x=8
