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 "onefourth" in the sentence, what do we do with that?

@jim_thompson5910 okay, i got (9.5,14.5)

so that's your point M

yup

jim_thompson5910

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)

not sure how you're getting that

just find the midpoint between (1,7) and (9.5, 14.5)

jim_thompson5910

so add up the coordinates, divide by 2

i mean would one point be 19?

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

5.25

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

jim_thompson5910
Best Response
You've already chosen the best response.
1
do the same for the y coordinates

ineedyouubiebs
Best Response
You've already chosen the best response.

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

jim_thompson5910
Best Response

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?

and what would we do if it was asking for the 1/2 of the way?

Add in the midpoint

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

so would the final answer be 5.25 or 10.75

in retrospect, i should have named the quarter point Q, oh well

jim_thompson5910
Best Response

they are used together to report the answer

jim_thompson5910
Best Response
You've already chosen the best response.
1
since all points are of the form (x,y)

ineedyouubiebs
Best Response
You've already chosen the best response.

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?

jim_thompson5910
Best Response
You've already chosen the best response.
1
each and every point on a 2D coordinate grid is always of the form (x,y)

jim_thompson5910
Best Response
You've already chosen the best response.

so you need both x and y to figure out where you are on this grid
