The distance between points (1, 2) and (x1, y1) is the square root of (x1 - 1)2 + (y1 - 2)2. a. true b. false

Question says that "The distance between points (1, 2) and is the square root of ."

It indicates that we need to find distance between given points (1, 2) and using distance formula then verify if the given answer is true or false.

Distance formula is

where (x1,y1) and (x2,y2) are usually given points.

Given that we have to use point (1,2)

so x2=1 and y2=2

plug these values into distance formula

Which is same as the given equation for distance.

Hence given statement is TRUE.
