question 6 -is 14/17
question 7 - is 10.7
Answer: 71.6°
tan-1(9/3) = 71.56505118°
I believe the correct answer from the choices listed above is option C. The slope of the green line would be -4/3. Parallel lines <span> are </span>lines<span> in a plane which do not meet; that is, two </span>lines<span> in a plane that do not intersect or touch each other at any point. These lines should have equal slopes. Hope this answers the question.</span>
