Question

To rotate a figure 180 degrees about the origin, which of the following must happen?
Select one:
a. Switch the coordinates and multiply both by –1
b. Multiply both coordinates of each point by –1
c. Switch the coordinates and multiply the first coordinate by –1
d. Multiply the first coordinate by –1

Answer 1

Answer 2

So for instance, a figure that is in Quadrant I is rotated 180 degrees. It would now reside in Quadrant III.

Answer 3

ok what else do i do

Answer 4

ok i got b for that one

Answer 5

Consider the following set of data points.
{(–2, 6), (0, 3), (4, 0), (8, –5)}

What is the domain?
Select one:
a. {6, 3, 0, –5}
b. {–2, 0, 4, 8}
c. (0, 3)
d. (4, 0)

Answer 6

can you help with this one

Answer 7

Then you look at the signs of the x and y coordinates in each quadrant. And the choice above that changes the signs correctly is the right choice. b is the right choice for that one.

Answer 8

Each question has to be posted separately.
