And number one, we have the rule, take all the order pairs, add 7 to the x's, and subtract 3 from the y's.
00:12
So from the graph, actually we're given, if j is at negative 6 ,6, k is at negative 3, 7, and l is at negative 1 3, and m is at negative 8, 0, we can just apply.
00:37
Rule, add 7 to the x's, so negative 6 plus 7 is 1, subtract 3, 6 minus 3 is 3.
00:48
K prime, if we add 7, we get 4.
00:52
If we subtract 3, we get 4.
00:54
So k prime is at 4, so you can go plot those points.
01:02
L prime, add 7, subtract 3, and m prime add 7, subtract 3.
01:13
Number two, a square has the vertices r at negative 2, 1, s at 3, 4, t at 6 negative 1, and you at 1 negative 4, you can tell you where they're going to go based on the vector, negative 4, negative 1, which means subtract 4, subtract 1.
01:48
So negative 2 minus 4 is negative 6, 1 minus 1 is 0.
01:54
Subtract four, subtract one, subtract four, subtract one, subtract four, subtract one, subtract four, subtract one.
02:09
We want to write a rule by observing the point, so i'm just going to note for you, for instance, d, i notice, is at 8, 4, and it's going to go to d prime, which is at negative 1, 8.
02:39
We just need to pick one pair.
02:41
And so the coordinate notation would be the rule x, y, goes to, to get from 8 to negative 1, we're going to subtract 9.
02:54
And to get from 4 to 8, we're going to add 4 to the y's...
