Answer:

  • y = -4x + 7

Step-by-step explanation:

Given points:

  • A(-2, -2) and B(6, 0)

The perpendicular bisector passes through the midpoint.

Finding the coordinates of the midpoint first:

  • x = (-2 + 6)/2 = 2, y = (-2 + 0)/2 = -1

Next finding the slope of AB:

  • m = (0 - (-2))/(6 - (-2)) = 2/8 = 1/4

The perpendicular lines have negative-reciprocal slopes.

The line will have a slope of -4 and pass through the point (2, -1)

  • y  - (-1) = -4(x - 2)
  • y + 1 = -4(x - 2)         - point-slope form
  • y = -4x + 7                - slope-intercept form
