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!

I will be happy to critique your thinking.
