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
