Question

What is the length of segment RS

Answer 1

I see that it's length is 12 boxes (im learning the same thing right now)

Answer 2

Answer: 13 units

Explanation:

From the given graph , the coordinates of point R = (-4,-3)

The coordinates of S = (1,9)

The distance formula to calculate distance between two points (a,b) and (c,d) is given by :-

`d=√((d-b)^2+(c-a)^2)`

Now, the distance between (-4,-3) and (1,9) is given by :-

`d=√((9-(-3))^2+(1-(-4))^2)\\\\\Rightarrow\ d=√((12)^2+(5)^2)\\\\\Rightarrow\ d=√(169)=13\text{ units}`

Hence, the length of line segment RS
`=13\text{ units}`
