Homework: What is the slope of a line perpendicular to the line 2y=x+5? I tried to find it, but the answer of 1/2 is wrong. Can anyone help please?

TheSmartOne (thesmartone):

The slope of this line is 1/2

TheSmartOne (thesmartone):

The slope of a line perpendicular is the negative reciprocal of this slope So reciprocal of 1/2 is 2 and negative so -2
