Answer:
x = 5
Step-by-step explanation:
These points have the same x-coordinate, so are on the same vertical line:
x = 5
Answer:
-7/10
Step-by-step explanation:
To find the slope of a line, you need to find the 
between two points. I will be using the points (-3, 5) and (7, -2).
= 
= 
= -7/10
Parallel lines always have the same slope. In fact that is the definition of parallel lines :P (Technically they have the same slope and different y-intercepts, because parallel lines can never intersect...)
