Answer:
3: D - Undefined
4: A - 1
Step-by-step explanation:
For Question 3 your answer is D, undefined, because it does not have a slope, a slope is like a hill, but that just goes straight up, thus it is undefined.
For Question 4 your answer is A, 1, because it moves one digit to the right and then 1 digit up, Thus that is your answer.
