Question

What is the approximate distance from (-2,3) to (4,1)?

5 units

6 units

8 units

9 units

Answer 1

draw it on graph paper then make a triangle and use the pythagorean theorum

Answer 2

or distance formula

Answer 3

ok thanks!

Answer 4

the formula is
\[d= \sqrt{(yb-ya)²+(xb-xa)²}\]
so
\[d= \sqrt{(1-3)²+(4-(-2))²}\]\[d= \sqrt{(-2)²+(6)²}\]
\[d= \sqrt{40}\approx6u\]

Answer 5

Btw, make a triangle and use the pythagorean theorum or formula is the same thing
this formula comes from pythagorean theorum based on the triangle formed by those two point and a third one (chose to make a right angle)
