Question

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 ____. (Input numbers and decimal point only, such as 8.2.)

Answer blank 1:

Answer 1

$d = \sqrt{ (x_{2} - x_{1})+ (y_{2}- y_{1} )$
$d = \sqrt{ ((2) - (2))+ ((2.5)- (1.2))$
$d = \sqrt{ (0)+ (1.3)$
$d= \sqrt{1.3}$
$d=1.1401754251$
Round up or down
$d=1.1$
