no.26,27,&29 aj yaa,yg lain gk ush.tolong yaa atas bantuannya pliss

26. aku gk tau
27. m = (y2 - y1) / (x2 - x1)
      m = (-8 + 3) / (3 - 5)
      m = -5/-3 = 5/3
29. m = -2
      m2 = -1/m1
      m2 = -1 / -2 = 1/2
      persamaannya
      y - y1 = m (x - x1)
      y + 2 = 1/2 (x - 2)
      2 (y + 2) = 1 (x - 2)
     2y + 4 = x - 2 
     2y + 4 - x + 2 = 0
Maaf ya, yg nomer 26 nya aq gk tau..
