The given equation of the line is in slope-intercept form which is generally expressed as y = mx + b. m and b are the slope and y -intercept, respectively. The slope of the given line is 2. The line perpendicular to this has a slope of -1/2. The line has the equation,
y - 1 = (-1/2)(x - -8)
Simplifying the equation gives,
y = (-1/2)x - 3
Thus, the answer is letter A.
