Hope that is it for you.

Answer 2

Answer: 5 units

Explanation:

Distance formula to calculate the distance between two points (a,b) and (c,d) is

`\text{Distance}=√((c-a)^2+(d-b)^2)`

Now, the distance between points P(4, 6) and Q(8, 9) is given by :-

`\text{Distance}=√((8-4)^2+(9-6)^2)\\\\\Rightarrow\text{Distance}=√(4^2+3^2)\\\\\Rightarrow\text{Distance}=√(16+9)\\\\\Rightarrow\text{Distance}=√(25)\\\\\Rightarrow\text{Distance}=5\ units`

Hence, the distance between points P(4, 6) and Q(8, 9) is 5 units.
