00:00:00.820 --> 00:00:04.170
（ 4 , -1 ）をグラフ上に点で示し
また その点が

00:00:04.170 --> 00:00:07.140
第一から第四のどの象限に位置しているか選びなさい

00:00:07.140 --> 00:00:09.700
えっと この数の組の最初の数である 4 が

00:00:09.700 --> 00:00:11.130
x 軸方向の位置を表していて

00:00:11.130 --> 00:00:14.890
水平方向 または x 軸方向にどれだけ進むかを教えてくれます

00:00:14.890 --> 00:00:16.260
それが 正の数の 4 ですから

00:00:16.260 --> 00:00:18.440
右に 4 つ進みます

00:00:18.440 --> 00:00:20.030
そして 数の組の2番目の数は

00:00:20.030 --> 00:00:21.654
垂直方向にどう動くかを教えてくれます

00:00:21.654 --> 00:00:23.110
言い換えると y 軸方向ですね

00:00:23.110 --> 00:00:24.600
それが -1 です

00:00:24.600 --> 00:00:26.480
これは負の数ですから
下に降りていきます

00:00:26.480 --> 00:00:29.280


00:00:29.280 --> 00:00:32.640


00:00:32.640 --> 00:00:34.260


00:00:34.260 --> 00:00:36.860


00:00:36.860 --> 00:00:38.810


00:00:38.810 --> 00:00:40.410


00:00:40.410 --> 00:00:41.940


00:00:41.940 --> 00:00:43.400


00:00:43.400 --> 00:00:45.330


00:00:45.330 --> 00:00:49.560


00:00:49.560 --> 00:00:51.560


00:00:51.560 --> 00:00:56.280


00:00:56.280 --> 00:00:58.930


00:00:58.930 --> 00:01:01.200


00:01:01.200 --> 00:01:03.490


00:01:03.490 --> 00:01:07.690


00:01:07.690 --> 00:01:09.690


00:01:09.690 --> 00:01:14.450


00:01:14.450 --> 00:01:17.740


00:01:17.740 --> 00:01:20.740


00:01:20.740 --> 00:01:22.626


00:01:22.626 --> 00:01:23.750


00:01:23.750 --> 00:01:25.470


00:01:25.470 --> 00:01:28.550


00:01:28.550 --> 00:01:30.530


00:01:30.530 --> 00:01:31.650


00:01:31.650 --> 00:01:34.660


00:01:34.660 --> 00:01:36.290


00:01:36.290 --> 00:01:39.760


00:01:39.760 --> 00:01:44.180


00:01:44.180 --> 00:01:46.170


00:01:46.170 --> 00:01:47.380


00:01:47.380 --> 00:01:49.380


00:01:49.380 --> 00:01:52.190


00:01:52.190 --> 00:01:55.460
