jawaban soal nomer 2
y -y1 = m ( x-x1)
y - 12 = 5/2 ( x - (-7))
y - 12 = 5/2 ( x + 7)
y - 12 = 5/2x + 35/2
y = 5/2x + 35/2 + 12 -------> sederhanakan X 2
2y = 5x + 35 + 24
2y = 5x + 59
m =
m =
m = 13/9
y-y1 = m(x-x1)
y+7 = 13/9(x-11)
y+7 = 13/9 x - 143/9
y = 13/9 x - 143/9 - 7
y = 13/9 x - 143/9 - 63/9
y = 13/9 x - 206/9
no 2
y-y1 = m(x-x1)
y-12 = 5/2(x+7)
y-12 = 5/2 x + 35/2
y = 5/2 x + 35/2 + 12
y = 5/2 x + 35/2 +24/2
y = 5/2 x + 59/2
----------------------- x 2
