Which of the following would be a line of reflection that would map ABCD onto itself? Square ABCD with C at 1 comma 3, D at 1 comma 1, A at 3 comma 1, and B at 3 comma 3. y = 1 2x + y = 2 x + y = 4 x + y = 1

  x + y = 4

Step-by-step explanation:

Any line of symmetry will be a suitable line of reflection. Lines of symmetry connect the midpoints of opposite sides, and connect opposite vertices.

The line AC will be a line of reflection that maps the square to itself. Its equation is ...

  x + y = 4 . . . . . . . 3rd choice

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
