5dregensleyerjawaban 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
jawaban soal nomer 3 y - y1 = m ( x-x1) y - (-4) = -4( x - (-2)) y + 4 = -4x - 8 y = -4x - 8 - 4 y = -4x - `12
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
jawaban soal nomer 3
y - y1 = m ( x-x1)
y - (-4) = -4( x - (-2))
y + 4 = -4x - 8
y = -4x - 8 - 4
y = -4x - `12
