Question 1: Explain why the equation of the line y=5 has a slope that is undefined. Explain in words or mathematically.

Question 2: Given any circle, the coordinates of one endpoint of a diameter is (3,-2). If the coordinates of the center are (2,-4), find the coordinates for the other endpoint.

Question 3: Explain what the difference is between a slope that is undefined and a slope of 0. Use mathematical reasoning to explain your answer.

THANKS!
