Hi,

Using the standard slope-intercept form for an equation of a line y = mx + b

  where m is the slope and b the y-intercept. 

 Which of the following is an equation of a line perpendicular to y= x-1 

y= x-1   slope m = 1

Perpendicular lines have slopes that are negative reciprocals of one another...

 Any line with slope m = -1 would be Perpendicular. 

Selection E has slope m = -1
