I need help for these three problems, thank you.

4. 0

5. -2

6. 3/2

Step-by-step explanation:

when you already have the line rise/run method is the easiest!  start at one point and then move either up/down (up is positive down is negative) and record the spaces you move, and then move to the right, record in the spaces you moved.  put it as a fraction, the amt you moved up/down as the numerator and the amt u moved right as the denominator. keep in mind the numbers on the axes! remember to simplify!

look up "slope dude" on yt for help with 0 and undefined

hope this helps!
