Question

Point R is located at (1, 2) on a coordinate grid. Point S is located at (4, 5) on the same

coordinate grid. What is the distance from point R to point S, rounded to the nearest tenth?

A. 3.2 units

B. 4.6 units

C. 7.6 units

D.

10.0 units

Answer 1

C. 7.6 units

Hope it helps!

Answer 2

4.2 units

most likely answer choice B

Explanation:

(1, 2) and (4, 5)

To find the distance between two points, we use the distance formula:

`d = \sqrt{(x_(2)-x_1)^2 + (y_2-y_1)^2 }`

Let's plug in what we know.

`d = √((4 - 1)^2 + (5 - 2)^2 )`

Evaluate the parentheses.

`d = √((3)^2 + (3)^2 )`

Evaluate the exponents.

`d = √((9) + (9) )`

Add.

`d=√(18)`

Evaluate the radical.

d = 4.24

Round to the nearest tenth.

d = 4.2 units

*note: The answer choice is 4.6. I'm not sure if that is a typo on someone's end, but the distance between these two points is exactly 4.24264068712 units.

Hope this helps!
