△xyz was reflected over a vertical line, then dilated by a scale factor of , resulting in △x'y'z'. which must be true of the two triangles? check all that apply

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
