Question

Point R is at (3, 1.3) and Point T is at (3, 2.4) on a coordinate grid. The distance between the two points is ____. (Input numbers and decimal point only, such as 8.2.) (Please walk me through how you got your answer!)

Answer 1

`RT = 1.1`

Explanation:

Distance between R(3, 1.3) and T(3, 2.4):

`RT = √((x_2 - x_1)^2 + (y_2 - y_1)^2)`

`RT = √((3 - 3)^2 + (2.4 - 1.3)^2)`

`RT = √((0)^2 + (1.1)^2)`

`RT = √(0 + 1.21) = √(1.21)`

`RT = 1.1`
