Aschool is planning for an addition in some open space
next to the current building. the existing building ends at
the origin. the graph represents the system of equations
that can be used to define the space for the addition. what
is the system of equations that matches the graph?

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.
