-3 - (-7) * A. Start at 0. Move to the left until you reach -3. Move to the left until you reach -10.
B. Start at 0. Move to the left until you reach -3. Move to the right until you reach 4.
C. Start at 0. Move to the right until you reach 3. Move to the left until you reach -4.
D. Start at 0. Move to the right until you reach 3. Move to the right until you reach 10.

B

Step-by-step explanation:

If you just do the equation, it will be -3+7 or 7-3, aka 4.

Next you will look at the answers,

And you will see -10, 4, -4, and 10.

Of course, we have calculated the answer is 4

So therefore the correct answer will be B.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
