To find the new coordinates of a point after a translation, we need to add the same amount to the x-coordinate and the y-coordinate. In this case, since the line is translated up 3 units and to the right 2 units, we will add 2 to the x-coordinate and 3 to the y-coordinate.

For the point (1,-5), adding 2 to the x-coordinate gives us 1+2 = 3, and adding 3 to the y-coordinate gives us -5+3 = -2. So the new coordinates for this point are (3,-2).

For the point (4,-4), adding 2 to the x-coordinate gives us 4+2 = 6, and adding 3 to the y-coordinate gives us -4+3 = -1. So the new coordinates for this point are (6,-1).

Therefore, the correct answer is A. (3,-2) and (6,-1).
A line containing the points (-2,3) and (2,3) is reflected across the x-axis. How long is the reflected line?
A. not enough information
B. 3 units
C. infinitely long
D. 4 units
When a line is reflected across the x-axis, the y-coordinates of the points on the line change sign, while the x-coordinates remain the same.

The original line contains the points (-2,3) and (2,3). The reflection of these points across the x-axis would be (-2,-3) and (2,-3).

The two reflected points (-2,-3) and (2,-3) lie on the same horizontal line with a y-coordinate of -3. Therefore, the distance between the two points is 2 units.

Therefore, the correct answer is D. 4 units.
A line segment has endpoints (2,-1) and (5,-4). What are the new endpoints after rotating the segment 90 degrees clockwise?
A. (-2, 1) and (-5, 4)
B. (2, -1) and (4,5)
C. (-1, -2) and (-4,-5)
D. (-2,-1) and (-5,-4)
To rotate a point 90 degrees clockwise, we need to swap the x and y coordinates and change the sign of the new x coordinate.

For the first endpoint (2, -1):
- Swapping the x and y coordinates gives us (-1, 2).
- Changing the sign of the new x coordinate gives us (-1, -2).

For the second endpoint (5, -4):
- Swapping the x and y coordinates gives us (-4, 5).
- Changing the sign of the new x coordinate gives us (-4, -5).

Therefore, the new endpoints after rotating the line segment 90 degrees clockwise are (-1, -2) and (-4, -5).

The correct answer is C. (-1, -2) and (-4, -5).
A rectangle has a side that is 10 units long. How long will this side be after the figure is translated down 4 units and to the right 5 units?
__ units
If a rectangle has a side that is 10 units long, the length of that side will remain the same after a translation. Translating the figure down 4 units and to the right 5 units will only change its position, not its size.

Therefore, the length of the side will still be 10 units.

The side will be 10 units long.
A rectangle with a vertex at (8, -2) is translated 3 units down. What are the coordinates of this vertex after it is translated?
To translate the rectangle 3 units down, we need to subtract 3 from the y-coordinate of the vertex.

The original vertex is (8, -2). Subtracting 3 from the y-coordinate gives us -2 - 3 = -5.

Therefore, the coordinates of the vertex after it is translated 3 units down are (8, -5).
Coordinates: H (-3, 6), I (-1, 4), J (-1, 1), K (-4, 1), L (-5, 4)
Translated the figure HIJKL 3 units to the left. Which of the following would be a vertex in the translated figure?
A. (-6, 6)
B. (2,4)
C. (-1,-2)
D. (-7, 4)
To translate a figure 3 units to the left, we subtract 3 from the x-coordinates of each vertex.

The original vertices are:
H (-3, 6)
I (-1, 4)
J (-1, 1)
K (-4, 1)
L (-5, 4)

After translating 3 units to the left, the new vertices would be:
H (-3 - 3, 6) = (-6, 6)
I (-1 - 3, 4) = (-4, 4)
J (-1 - 3, 1) = (-4, 1)
K (-4 - 3, 1) = (-7, 1)
L (-5 - 3, 4) = (-8, 4)

Among the given options, the vertex that matches one of the translated coordinates is:
A. (-6, 6)

Therefore, the correct answer is A. (-6, 6).
