What is the slope of a line perpendicular to the line whose equation is 2x-y=5 fully reduce your answer

9514 1404 393

  -1/2

Explanation:

Solving the equation for y, we can find the slope of the given line. It is the coefficient of x.

  y = 2x -5 . . . . . slope = 2

The slope of the perpendicular line will be the opposite reciprocal:

  m = -1/2 . . . . . slope of perpendicular line

the answer is b. apsidal precession

reflecting point a across the origin negates both of its coordinates.

b = (5, -4)
