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:
[tex] RT = 1.1 [/tex]
Step-by-step explanation:
Distance between R(3, 1.3) and T(3, 2.4):
[tex] RT = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
[tex] RT = \sqrt{(3 - 3)^2 + (2.4 - 1.3)^2} [/tex]
[tex] RT = \sqrt{(0)^2 + (1.1)^2} [/tex]
[tex] RT = \sqrt{0 + 1.21} = \sqrt{1.21} [/tex]
[tex] RT = 1.1 [/tex]
