Explain whether or not the set of ordered pairs below is a function.
(4,2) (5,3) (6,2) (4,6)
It is NOT a function because the x value of 4 is mapping to more than one y-value (2 and 6).
Describe in words how to rotate a triangle 180o clockwise using a graph.
If it helps, use the points A(1,1), B(5,2), and C(3,8).
1) Plot the points.
2) Rotate your paper 180o clockwise.
3) Write down the coordinates of the triangle as if the x-y plane is normal.
4) Flip the paper back to normal and plot the coordinates you wrote down.
