PLEASE HELP!! 25 POINTS
△ABC is reflected to form △A′B′C′.
The vertices of △ABC are A(−7, 1), B(−5, −3), and C(−3, 2).
The vertices of △A′B′C′ are A′(−7, −1), B′(−5, 3), and C′(−3, −2).

Which reflection results in the transformation of △ABC to △A′B′C′?
A. reflection acros s the x-axis
B. reflection across the y-axis
C. reflection across y = x
D. reflection across y=−x

o, I first graphed the ORIGINAL points and then I reflected the ORIGINAL points across the x-axis and I found out that the points (not the original ones) didn't match. Then I reflection across they-axis and found out that the points match so its y-axis!!!

It is a reflection across the X-axis

Step-by-step explanation:

Graph the original points and also graph the new points and you will see the "new" points are over the X-axis!!

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.

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
