Answer:
I think they're neither perpendicular nor parallel
Explanation:
Not parallel since slope of e (3/5) isn't equal to slope of f (-8/3)
Not perpendicular since the product of their slopes isn't equal to - 1.
=> (3/5)(-8/3)= - 8/5 and not - 1 
(plz make sure you typed the equations correctly.)

D. “The scientific name Asteroidea was given to starfish by the French zoologist de Blainville in 1830. It is derived from the Greek aster, ἀστήρ (a star) and the Greek eidos, εἶδος (form, likeness, appearance). The class Asteroidea belongs to the phylum Echinodermata.”
E. “First, primates have larger eyes than many other mammals of comparable body size (Ross & Kirk, 2007). Having large eyes ensures that a large image is formed on the retina (Walls, 1942; Land & Nilsson, 2002). This large retinal image may then be sampled by many photoreceptors, improving visual resolution. Primates have flexible shoulder joints and and strong clavicles or collar bones that help them use their arms more effectively than other species of animals. Most primate can hold their bodies erect and some species, including humans, can walk on two legs instead of four.”
        
             
        
        
        
I think you wanted to know whether the statement in question is true or false. Based on this assumption, i am answering this question and hope that it helps you. It is absolutely true that the slash and burn system of deforestation reduces the number of oxygen producing and puts more carbon in the air.
        
                    
             
        
        
        
Answer: The exoplanets are the planets which orbit stars other than the sun.
Explanation: Exoplanets are also known as extra solar planets which means that these planets revolve or orbit around the stars other than the sun.
Exoplanets does not belong to our solar system because in our solar system, the planets orbit around the star named as sun.
Examples of exoplanets are Kepler-186f , 55 Cancri e.
