Question

Tolong yaa pakai caranya
makasihh

Answer 1

2x + y - 3 = 0
refleksi terhadap O(0,0)

x' = -x ---> x = -x'
y' = -y ---> y = -y'

Hasil refleksi
2x + y - 3 = 0
2(-x') + (-y') - 3 = 0
-2x - y - 3 = 0
2x + y + 3 = 0

titik potong dg sb x ---> y = 0
2x + y + 3 = 0
2x + 0 = -3
x = -3/2

titik potong = (-3/2,0)
