Question

Find the distance between points m(-4,6) and n(10,-5). round to the nearest tenth if necessary.

Answer 1

use the distance forumla
d=
`√((x1-x2)^2+(y1-y2)^2)`
subsitute
x1=-4
x2=10
y1=6
y2=-5

d=
`√((-4-10)^2+(6-(-5))^2)`

d=
`√((-14)^2+(6+5))^2)`

d=
`√((-14)^2+(11))^2)`

d=
`√(196+121)`

d=
`√(317)`
d=aprox 17.8045
if on a test, put √317
