Hi,

What is the slope of the line that is perpendicular to the line whose equation is 

2x + y = 4    |the standard slope-intercept form for an equation of a line is y+=+green%28m%29x+%2B+b

0r  y = highlight%28-2%29x + 4,   m = -2

line that is perpendicular to this line:  m =  highlight_green%281%2F2%29

Note:   %28-2%29%281%2F2%29+=+-1+
