<span>The answer is the third statement. "The triangles are congruent because triangle R'S'T' is a rotation of triangle RST and rotation in a rigid motion" The triangles are congruent because the image is a rotation (There is a rotation of 180 degrees) of the original and a rotation is a rigid motion. The best way to test it out is to assign values to the points for points R, S, and T and then apply the rule to see where the new image will be. </span>
28/5, you cross multiply so 4/5=y/7 would become 5y=28 then you solve for y from there which becomes 28/5
First plug the point ans slope into the point slope form which is y-y1=m(x-x1)
y-1=2(x-(-2))
Simplify
y-1=2(x+2)
