Answer:

Step-by-step explanation:

Based on the table, it would not have been from a linear function. To have a linear function, the x and y values would have to be increasing/decreasing at a constant rate.

This is the change from the first (x, y) pair to the second. Now, let's see if the next has the same change:

-7+4=-3

4-3=1

-3+4=1

3-2=1

Now, let's check the last one:

1+6=7

2-1=1

The y value is still changing by -1, but the x value has been increased by a different amount, therefore it is NOT a linear function.

Rotate triangle P 90° clockwise about the point (2, -1).<br>

dlinn [17]

Answer:

Step-by-step explanation:

If we are rotating about the point (2,-1) , then we first need to translate the triangle two points to the left so that point P is at location (2,-1). Once we have that we rotate everything 90 degrees clockwise, while maintaining the same distance and angles between each point in the triangle. After doing this we will get the triangle seen in the attached picture below. Which is fully rotated 90 degrees clockwise about the point (2,-1)
