Point R is at (2, 1.2) and Point T is at (2, 2.5) on a coordinate grid. The distance between the two points is

Sergeu [11.5K]

<h3>Answer: 1.3</h3>

========================================

Work Shown:

The two points we have are $(x_1,y_1) = (2,1.2)$ and $(x_2,y_2) = (2,2.5)$

Apply the distance formula

$d = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\\\\d = \sqrt{(2-2)^2+(1.2-2.5)^2}\\\\d = \sqrt{(0)^2+(-1.3)^2}\\\\d = \sqrt{0+1.69}\\\\d = \sqrt{1.69}\\\\d = 1.3\\\\$

-------------------------

A shortcut is possible by subtracting the y coordinates of the two points, and making the result positive through the use of absolute value.

So we either say

|y1-y2| = |1.2-2.5| = |-1.3| = 1.3

or,

|y2 - y1| = |2.5 - 1.2| = |1.3| = 1.3

We get the same result. This shortcut is valid because the x coordinates of both points are the same.
