Question

Tentukan persamaan garis garis berikut
1. garis melalui titik (3,4) dengan gradien 2
2. garis melalui titik (-3, 5) dengan gradien 4

Answer 1

No 1
y-y1 = m(x-x1)
y-4 = 2(x-3)
y-4 = 2x-6
y = 2x-6+4
y = 2x-2

no 2
y-y1 = m(x-x1)
y-5 = 4(x+3)
y-5 = 4x+12
y = 4x+12+5
y = 4x+17

Answer 2

jawaban soal nomer 1
y-y1 = m(x-x1)
y-4 = 2(x-3)
y-4 = 2x-6
y = 2x-6+4
y = 2x-2

jawaban soal nomer 2
y-y1 = m(x-x1)
y-5 = 4(x+3)
y-5 = 4x+12
y = 4x+12+5
y = 4x+17
