<h3>Answer: Choice C 
</h3>
The open circle means we do not include the endpoint, hence the use of a greater than symbol. If we were to include the endpoint, then we'd have greater than or equal to. We can rule out choice B due to this reasoning.
The ray pointing to the right indicates we are talking about x values larger than 5, so we can rule out choice A and conclude the answer is C.
Side note: The notation is saying "x is a real number"
Answer:
Slope of line 1 = 3
Slope of line 2 = 3
Slope of line 3 = -1/3
Line 1 and 2 are parallel
Line 1 and 3 are perpendicular
Line 2 and 3 are perpendicular
Step-by-step explanation:
Find the slope of each line by using this equation:
lines are parallel if they have the same slope and line are perpendicular in they have opposite reciprocal slopes. (-1/3 is the opposite reciprocal of 3).
Hope this helps!
