Answer:
By definition, the slope of a vertical line is undefined. Because the value of x is always equal to 4 it is never equal to 0 therefore there is no y-intercept.
Step-by-step explanation:

(X÷2)-12
This is because you break the problem down.
For example half = divide by 2
Gave out= minus
Hope it helps
For number 16, keep the slope and plug in the values of x and y and solve for the y intercept. For 20 take the opposite reciprocal and then plug in the values of x and y and solve for y intercept. For number 24 and 25 convert both into slope intercept form (y=mx+b) and see if they are parallel or perpendicular
The domain 2 would be plugged in as f (2)=2x+1 which equals 5
