Bro I don't know how to do this and I really need help, ill give brainiest.

B

Step-by-step explanation:

Because they took the correct steps to answer the equation.They also got the right answer (-2).

At the begining they added 4 to both sides (to cancel out the 4)

C would be wrong because they subtracted 4 from a negative four and this does NOT cancel it out.

Have a day, I hope you like my explination. If you do I would appreciate if you gave rating or brainliest :)

six digits cordnate grids are gayyy

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
