Question

Nomor 17 dan 18 pakai cara tolong dibantu ya

Answer 1

17 . f(x) = px + q

f(3) = 3p + q = 13
f(-1) =-1p +q = -7  -
      4p      =20
         p      = 5
f(3) = 3(5) +q
13 = 15 + q
13 - 15 = q
-2 = q

f(-3) = -3(5) + (-2)
       = -15 -2 =-17
jadi , jawabannya A

18.  A(-3,4) , B(2,-5)

   y- y1 =  x- x1
y2-y1      x2-x1
y -  4 = x -(-3)
-5 - 4    2- (-3)
y-4 = x +3
-9        5
5y - 20 = -9x -27
5y +9x - 20 +27 =0
5y + 9x + 7 =0
 jawabannya D

 maaf kalo salah :)
