Perpendicular lines have negative reciprocal slopes.
2y=x%2B5
y=%281%2F2%29x%2B5%2F2
So,
m=1%2F2
m%5Bp%5D%2A1%2F2=-1
highlight%28m%5Bp%5D=-2%29

the slope of a line perpendicular to the line 2y=x%2B5
first find the slope of given line
2y=x%2B5
y=x%2F2%2B5%2F2
y=%281%2F2%29x%2B5%2F2 => the slope is m=1%2F2
the slope of a line perpendicular line m%5Bp%5D is negative reciprocal to m
m%5Bp%5D=-1%2F%281%2F2%29
m%5Bp%5D=-1%2A2%2F1
m%5Bp%5D=-2...the slope of a line perpendicular line
