a) What is the equation of line A
b) What is the equation of line B

Answer:
the equation of line a is y = 4
The equation of line b is x=8
Step-by-step explanation:
Line A -is a horizontal line with no slope - for every value of x no matter what x is - y= 4
Line B has an infinite slope because it is vertical
For every value of y - no matter what y you choose x= 8 So the equation of the line is x=8
