1
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

2
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

3
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

4
00:00:09,700 --> 00:00:11,130
x 軸方向の位置を表していて

5
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

6
00:00:14,890 --> 00:00:16,260
それが 正の数の 4 ですから

7
00:00:16,260 --> 00:00:18,440
右に 4 つ進みます

8
00:00:18,440 --> 00:00:20,030
そして 数の組の2番目の数は

9
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

10
00:00:21,654 --> 00:00:23,110
言い換えると y 軸方向ですね

11
00:00:23,110 --> 00:00:24,600
それが -1 です

12
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

13
00:00:26,480 --> 00:00:29,280


14
00:00:29,280 --> 00:00:32,640


15
00:00:32,640 --> 00:00:34,260


16
00:00:34,260 --> 00:00:36,860


17
00:00:36,860 --> 00:00:38,810


18
00:00:38,810 --> 00:00:40,410


19
00:00:40,410 --> 00:00:41,940


20
00:00:41,940 --> 00:00:43,400


21
00:00:43,400 --> 00:00:45,330


22
00:00:45,330 --> 00:00:49,560


23
00:00:49,560 --> 00:00:51,560


24
00:00:51,560 --> 00:00:56,280


25
00:00:56,280 --> 00:00:58,930


26
00:00:58,930 --> 00:01:01,200


27
00:01:01,200 --> 00:01:03,490


28
00:01:03,490 --> 00:01:07,690


29
00:01:07,690 --> 00:01:09,690


30
00:01:09,690 --> 00:01:14,450


31
00:01:14,450 --> 00:01:17,740


32
00:01:17,740 --> 00:01:20,740


33
00:01:20,740 --> 00:01:22,626


34
00:01:22,626 --> 00:01:23,750


35
00:01:23,750 --> 00:01:25,470


36
00:01:25,470 --> 00:01:28,550


37
00:01:28,550 --> 00:01:30,530


38
00:01:30,530 --> 00:01:31,650


39
00:01:31,650 --> 00:01:34,660


40
00:01:34,660 --> 00:01:36,290


41
00:01:36,290 --> 00:01:39,760


42
00:01:39,760 --> 00:01:44,180


43
00:01:44,180 --> 00:01:46,170


44
00:01:46,170 --> 00:01:47,380


45
00:01:47,380 --> 00:01:49,380


46
00:01:49,380 --> 00:01:52,190


47
00:01:52,190 --> 00:01:55,460
