Question

points a2,3 and b5,9 round to the nearest tenth

Answer 1

what do you mean... like are you trying to find the midpoint or what?

Answer 2

i am guessing it is
"find the distance between the points \((2,3)\) and \((5,9)\)

Answer 3

yes

Answer 4

from 2 to 5 in the x direction is right 3 units
from 3 to 9 in the y is up 6
pythagoras gives the distance as
\[d^2=3^2+6^2=9+36=45\] and so
\[d=\sqrt{45}\]

Answer 5

you are welcome to use the distance formula if you like
\[d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\] but the idea is pythagoras
