Note: It seems you have asked the exact same type of questions again and again. So, I will solve the first question. The rest of the questions is the carbon copy of the same concept and solution method. Hopefully, it would get your concept clear.
Answer:
The distance between the points (3, 6) and (8, -1)
Explanation:
Given the points
Finding the distance between the points (3, 6) and (8, -1)
(x₁, y₁) = (3, 6)
(x₂, y₂) = (8, -1)





Thus, the distance between the points (3, 6) and (8, -1)
NOTE: All the remaning questions have the same method of solution.
