Would appreciate some with this quick question.

c

Step-by-step explanation:

function is when the two points meet up at the same points if it was 1 to 1 it would match but it doesn't so it's c

:D Hoped this helped <3

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

4th option is correct xy=-10

if this was to u plzz mark me the brainliest
