Which transformation produces similar but not congruent figures?

dilation by a scale factor of 1.5

rotation 270 degrees
counter-clockwise

translation up 2 units and left 5

reflection over the y-axis

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

noncoplanar points are points that do not lie on the same line.
