ok ... what does the SLOPE of the line perpendicular to \(\large y=2x+1\) have to be??
OpenStudy (anonymous):
2
OpenStudy (paxpolaris):
no, if two lines have the same slope they are parallel to each other.... not PERPENDICULAR
OpenStudy (paxpolaris):
the slope of the PERPENDICULAR line is the NEGATIVE RECIPROCAL of the original slope so it should be\[\Large -\frac12\]

i did thanks all
