00:02
1, 4, 4, and 2 .4.
00:09
On the coordinate plane, name the figure formed.
00:13
So this would be a triangle.
00:19
Multiply each y coordinate by negative 1.
00:22
Graph the points.
00:23
How is the triangle related to the 1 in exercise 1? so i'm just going to change my color for it.
00:28
Oops.
00:31
Okay.
00:32
So multiply each y coordinate by negative 1.
00:35
So i would have 1 comma negative 1.
00:39
4 comma negative 4 and then i would have 2 comma negative 4 so 1 negative 1 4 4 negative 4 and 2 negative 4 and the it forms a triangle that is a reflection to number 1 multiply each coordinate in exercise 1 by negative 1 graph the points so i'm just going to change my pen color again i'll do red.
01:16
So then i have negative 1 comma negative 1.
01:19
I have negative 4 comma negative 4 and then negative 2 negative 4.
01:28
And so i would be at negative 1, negative 1, negative 4, negative 4 and negative 2 negative 4.
01:39
And so that is the shape right there.
01:42
What would you have to do to get the coordinates of a triangle in quadrant 2? congruent to the ones in exercise one through three.
01:53
So you could do a reflection across the y -axis.
02:04
Okay.
02:05
And because number two was a reflection across the x -axis.
02:16
Graph points 3 -1, so over 3 up 1, 2, 3, 4, 6, 4, 6.
02:27
And 5 -4 on the coordinate plane.
02:36
Okay.
02:38
Connect the dots.
02:39
The figure formed is called a parallelogram.
02:41
Yes, that is true.
02:42
Add two to both coordinates of each point and then graph the new coordinates.
02:47
Name the figured form.
02:49
So i'll do blue this time.
02:54
So my new coordinates would be, if i add two to each one, it would be 5, 3, 4, five, six, eight, and seven, six.
03:10
So five, three.
03:16
So over five, up three.
03:20
Ooh, i messed up on this one.
03:22
Hold on.
03:24
I didn't go up enough...
