1. Diketahui persamaan garis g = 2x - 3y = 7 ditranslasikan oleh T = (1,3) a. Tentukan persamaan bayangannya b. Gambarkan garis g dan bayangannya! . . kalo bisa

Transformasi
1. g -> 2x - 3y = 7
T(1,3) --> x' = x + 1 dan y' = y+ 3
x= x' - 1
y = y' - 3

2 (x ) - 3(y)= 7 --> 2 (x' -1)  - 3 (y' - 3) = 7
2x - 2 - 3y + 9 = 7
2x - 3y = 0

2. 
a)
A(5,4)  D(p,3] = A' (13,8)
Misl p(a,b)
(x', y') = { (3(x -a ) + a). (3(y-b) + b)

x' = 3(x - a )+ a -->13 = 3(5-a) + a-
13 = 15 - 3a + a
-2a = - 2
a = 1

y' = 3(y-b)  + b
18 = 3(4 -b) + b
18 = 12 - 3b + b
2b = -6
b = - 3
P(a,b)  = (1, -3)

b)
4x - y = 7  D{(1,-3) , -2)
x' = k(x-a) + a --> x' = -2(x - 1)  + 1
x' = -2x +2  + 1
x' = -2x + 3 --> x = -1/2 x'  + 3/2

y' = k(y-b) +b --> y' = -2(y+3) - 3
y' = -2y - 6 - 3 --> y' = -2y - 9
y = -1/2 y'' - 9/2

4x - y = 7 --> 4(-1/2 x' + 3/2) - (-1/2 y' - 9/2)  = 7
-2x' + 6 + 1/2 y' + 9/2 = 7 ....kalikan (-2)
4x - 12 - y - 9 = - 14
4x - y -7 = 0
