Question

Use the distance formula.
P(-2, 7) and Q(-6, 4)

Answer 1

When u know the formula, simply use it.

Answer 2

5

Answer 3

@saifoo.khan im trying to see if im correct, because my answer was \[\sqrt{-11}\]

Answer 4

formula
sqr root of [ (xsub2-xsub1)^2+(ysub2-ysub1)^2 ]

same for 3 dimensions except you include the variable z
sqr root of [ (xsub2-xsub1)^2+(ysub2-ysub1)^2 +(zsub2-zsub1)^2]

Answer 5

i could be wrong, havent looked to see

Answer 6

P(-2, 7) and Q(-6, 4)
d=√((x^2-x^1 )+(y^2-y^1 ) )
=√([-6-(-2) ]+(4-7))
=√(-8+3)
=√(-5)
=5


kk i see what i did wrong now.

Answer 7

over 4, down 3 pythagoras says it is
\[d^2=3^2+4^2=25\implies d = 5\]
