1 00:00:01,200 --> 00:00:06,803 Plot the ordered pair (6, -8) into the coordinate plane. 2 00:00:06,803 --> 00:00:09,311 So this is the coordinate plane over here: 3 00:00:09,311 --> 00:00:12,237 This is the horizontal axis over here is the x axis 4 00:00:12,237 --> 00:00:16,463 The vertical axis here is the y axis 5 00:00:16,463 --> 00:00:21,804 and the convention when we get an ordered pair like this 6 00:00:21,804 --> 00:00:24,961 is the first coordinate is the x coordinate 7 00:00:24,961 --> 00:00:28,119 and the second coordinate is the y coordinate 8 00:00:28,119 --> 00:00:31,463 So they're telling us we have an x coordinate of 6 9 00:00:31,463 --> 00:00:33,135 x coordinate of 6. 10 00:00:33,135 --> 00:00:36,897 that means we count up 6 on the x axis 11 00:00:36,897 --> 00:00:40,054 So let's count up 1, I can even write down 1 12 00:00:40,054 --> 00:00:42,655 then we have 2, that's right there 13 00:00:42,655 --> 00:00:46,695 then we have 3, then we have 4, then we have 5 14 00:00:46,695 --> 00:00:50,467 and then we have moved up 6 along the x axis 15 00:00:50,467 --> 00:00:53,150 we started at the origin 16 00:00:53,150 --> 00:00:55,472 at (0,0), that's the origin 17 00:00:55,472 --> 00:00:57,051 then we moved 6 to the right 18 00:00:57,051 --> 00:00:59,466 that's this part right over here [indicating 6 in (6,8)] 19 00:00:59,466 --> 00:01:02,485 Now our y coordinate is -8 20 00:01:02,485 --> 00:01:05,867 that means we move down 8 in the vertical direction 21 00:01:05,867 --> 00:01:09,126 so we can see it right over here 22 00:01:09,126 --> 00:01:10,565 I'll just do every 2. 23 00:01:10,565 --> 00:01:12,795 So this is down 1, this right here is -2 24 00:01:12,795 --> 00:01:16,138 -3, this right here is -4 25 00:01:16,138 --> 00:01:19,900 -5, -6, -7, -8 26 00:01:19,900 --> 00:01:26,448 So we move to the right 6 and down 8 27 00:01:26,448 --> 00:01:28,584 we move to the right 6 28 00:01:28,584 --> 00:01:32,810 then we move down 1, 2, 3, 4, 5, 6, 7, and 8 29 00:01:32,810 --> 00:01:36,897 and we are right over there 30 00:01:36,897 --> 00:01:42,377 so that is the point (6, -8) 31 00:01:42,377 --> 00:01:46,371 you can also move at it this way 32 00:01:46,371 --> 00:01:47,717 so you move 6 there 33 00:01:47,717 --> 00:01:49,111 so we will be along this line here 34 00:01:49,111 --> 00:01:51,804 and then you can go and then the y coordinate is -8 35 00:01:51,804 --> 00:01:55,705 and you say we will be along this line over here 36 00:01:55,705 --> 00:01:56,820 and the place they intersect is this coordinate 37 00:01:56,820 --> 00:02:00,488 the way i like to think of it move 6 to the right 38 00:02:00,488 --> 00:02:02,067 move along the x axis 39 00:02:02,067 --> 00:02:05,132 and then move along in the y axis 40 00:02:05,132 --> 99:59:59,999 so you go down 8
