-
The slope of the line is 2, and the line perpendicular to the original line always has a slope of the negative reciprocal of the original line's slope. So, the negative reciprocal of 2 is -1/2. So, the equation would be y=-1/2-5.

Perpendicular lines have slopes that are negative reciprocals of each other.
Therefore, a perpendicular line's slope would be -1/(2) = -1/2
Every perpendicular line will have the form y = -x/2 + c.
Replace c with any constant you want.
y = -x/2 + 4
Therefore, a perpendicular line's slope would be -1/(2) = -1/2
Every perpendicular line will have the form y = -x/2 + c.
Replace c with any constant you want.
y = -x/2 + 4
