Find the point that is one-fourth of the way from (1,7) to (18,22)
find the midpoint from (1,7) to (18,22) call this midpoint M
sorry for bothering you again you really help
once you have M, use this to find the midpoint from (1,7) to M
this works because the quarter point is exactly half way between the starting point and the midpoint
and what about the "one-fourth" in the sentence, what do we do with that?
look at my next post after that
so that's your point M
now you must find the midpoint from the starting point (1,7) to M(9.5, 14.5)
im lost, how would I do that?
the same way you found the midpoint between the two original points (ignore M)
Would it be
i think i have an idea
i cant write it in the equation button, but would it be 1+x^2
not sure how you're getting that
just find the midpoint between (1,7) and (9.5, 14.5)
so add up the coordinates, divide by 2
i mean would one point be 19?
how are you getting 19?
find the midpoint between (1,7) and (9.5, 14.5)
its a mess but i tried
(1+9.5)/2 = ???
can you please set it up into the formula. this is new stuff for me and tommorow i have a test based on this
what does (1+9.5)/2 evaluate to
so that's the x coordinate of the midpoint between (1,7) and (9.5, 14.5) ie...it's the x coordinate of the quarter point
do the same for the y coordinates
so for the y coordinates i would add 7+14.5 which will give me 21.5 and then divide it by 2 which will give me 21.5
21.5/2 = ??
you typed 21.5 twice
oops my bad its 10.75
yep, so the quarter point is (5.25, 10.75)
okay so will i always divide by 2? how do i know what do divide to? and would i always be adding as well?
we're just finding midpoints
a quarter point is a midpoint between the start and the original midpoint
and what would we do if it was asking for the 1/2 of the way?
Add in the midpoint |dw:1379390452778:dw|
now add in the point which is 1/4 way from P to Q, call this point N point N is the midpoint between P and M |dw:1379390509988:dw|
so would the final answer be 5.25 or 10.75
in retrospect, i should have named the quarter point Q, oh well
they are used together to report the answer
since all points are of the form (x,y)
so the final answer would be (5.25,10.75)
even though its just asking for 1 point? how do i know which point is it x or y?
each and every point on a 2D coordinate grid is always of the form (x,y)
so you need both x and y to figure out where you are on this grid
thanks so much!
