Answer:

  -1/2

Step-by-step explanation:

Rearranging this equation to slope-intercept form, we see the slope (x-coefficient) is 2:

  2x = 7 + y . . . . . add y

  y = 2x -7 . . . . . . subtract 7

The slope of the perpendicular line is the opposite of the reciprocal of this:

  -1/2 = slope of perpendicular
