Verified answer
Cara 1A + T = A'
(x, y) + (-3, 4) = A'
A' = (x - 3, y + 4)
x' = x - 3 »» x = x' + 3
y' = y + 4 »» y = y' - 4
maka persamaan bayangannya
3x - y + 1 =0
3(x'+ 3) - (y' - 4) + 1 = 0
3x' + 9 - y' + 4 + 1 = 0
3x - y + 14 = 0
cara 2
T (a, b)
px + qy = x + p(a) + q(b)
T (-3, 4)
3x - y = -1 + 3(-3) - (4)
3x - y = -1 - 9 - 4
3x - y = -14
3x - y + 14 = 0
