Base on the question where as asking to choose among the following point in your question that states the center of rotation if the triangle abc is rotated 180 degree, base on my calculation, the possible answer would be either point a, point b, or point c. I hope you are satisfied with my answer and feel free to ask for more
7. D
8. D
9. D
10.C
for 7 & 8 you use the equation
your points are (3,8) & (9,5)
so you plug the numbers in
y2= 5
y1=8
x2=9
x1=3
you subtract them get a fraction and that is your slope
9 & 10
use the equation
plug you numbers in for y1 and x2 m is your slope plug it in and that is your equation
That would be 7 - 1 = 6 turning points
