Free points cause I can

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.

i would pic false cause it goes down towards negative

step-by-step explanation:

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

r and t.
