2. Answer:
   

   
   

   y = x – 4
   

   
   

   Step-by-Step Explanation:
   

   
   

   Perpendicular lines have slopes that are negative reciprocals—multiplying their slopes result in -1.
   

   
   

   Given the slope of a line m = -1, then it means that the slope of the other line must be 1 (because multiplying the slope of line 1  (m1 = -1), and the slope of the other line (m2 = 1) results in: -1 × 1 = -1).
   

   
   

   Therefore, given the slope of line 2 (m2 = 1), and the point (2, -2), we could plug these values into the slope-intercept form and solve for the y-intercept (b):
   

   
   

   y = mx + b
   

   
   

   -2 = 1(2) + b
   

   
   

   -2 = 2 + b
   

   
   

   Subtract 2 from both sides to solve for b:
   

   
   

   -2 – 2 = 2 – 2 + b
   

   
   

   -4 = b
   

   
   

   Therefore, the y-intercept (b) = -4.
   

   
   

   Hence, the equation of the perpendicular line is: y = x – 4
