Which transformation or combination of transformations can be used to show that quadrilateral jklm with vertices j(8, 4), k(4, 10), l(12, 12), and m(14, 10) is congruent to quadrilateral wxyz with vertices w(8, -4), x(4, -10), y(12, -12), and z(14, -10)? a. a reflection b. a rotation c. a reflection followed by a dilation d. a stretch followed by a reflection e. a rotation followed by a dilation

The correct answer is:

A. a reflection

Explanation:

Each point (x, y) in the pre-image is mapped to a corresponding point (x, -y) in the image.  Since only the value of the y-coordinate changes, this is a reflection through the x-axis.

Step-by-step explanation:

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
