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.  
2x+7y=4  Or y = (-2/7)x + 4/7   m = (-2/7)
y=2x+5   m = 2
Are they Parallel,perpendicular,or neither? Neither
parallel have identical slopes
perpendicular have slopes that are negative reciproclas of one another:
  ex: m -2/7  and m = 7/2
