In this question, we're going to be finding the image of the point negative 5 4 under a rotation of 270 degrees clockwise about the origin.
00:14
Now let's catch the coordinate plane and place the point negative 5, 4 on the coordinate plane.
00:25
So negative 5, 4 is at 5 steps to the left, the x -axis, 1, 2, 3, 4 and 4 steps up.
00:35
2, 3, 4.
00:37
So this is a point negative 5, 4.
00:43
And the rotation is 270 degrees counterclockwise.
00:50
So that means we're moving in the anticlockwise direction.
00:56
So making a 270 degrees counterclockwise turn is equivalent to making a 90 degrees clockwise rotation.
01:09
So we want to use this as the center, which is the origin.
01:16
And just to visualize this we just have to draw some dotted lines here...
