Which best explains why y=y+1 has no solution?

Think of any number you want to replace y. Let's say you pick 3. So y = 3.

Replace every copy of y with that number 3. You will go from y = y+1 to 3 = 3+1

Then simplify the right side and you end up with 3 = 4, which is false. The number 3 is different from the number 4, so they can't be equal. This contradiction is one example (of many) that helps prove y = y+1 is false.

To prove that y = y+1 is false for every real number, you would subtract y from both sides like so

y = y+1

y-y = y+1-y

0y = 0y+1

0 = 0+1

0 = 1

and we have another contradiction here, so there is no way this equation has a solution. We say that this equation is inconsistent

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.
