How do you find the distance between (10,19), (-13,9)?

2 Answers

Use a2+b2=c2

c=25.1

Explanation:

Let the change in x be a2
Let the change in y be b2

The the square root of c2 = the distance

a2=(199)2

a2=100

b2=(1013)2

b2=529

100+529=629

629=c2

square root of 629=c

c=629

c=25.1

=25.08

Explanation:

The formula for the distance between two points is based on the Theorem of Pythagoras.

|AB|=(x2x1)2+(y2y1)2)

We have the points (10,19)and(13,9)

Distance = (10(13))2+(199)2

=232+102

=629

=25.08
