Best ResponseYou've already chosen the best response.1to find the midpoint, you take the average value of the xcoordinates, then the average value of the ycoordinates, then put them together to make a new point (xaverage,yaverage) we can use #19 as an example G(4,4) and H(6,4) the xcoordinates are 4 and 6, do you remember how to find the average?

Best ResponseYou've already chosen the best response.1almost but not quite 4+6 = 2, correct, but we divide by 2, not 3, since there are 2 points 2/2 = 1, with me so far?

Best ResponseYou've already chosen the best response.0lol sorry i dont know why i said 3 but yes

Best ResponseYou've already chosen the best response.1ok, now do the same thing with the ycoordinates the average of 4 and 4 is...?

Best ResponseYou've already chosen the best response.1right, so the midpoint is (1,4) can you try #2022 on your own? :) I'll guide you if you get stuck

Best ResponseYou've already chosen the best response.1yup, so our midpoint is...?

Best ResponseYou've already chosen the best response.0so that would be 1.5

Best ResponseYou've already chosen the best response.1yup, 1, so put them together

Best ResponseYou've already chosen the best response.0yup that one i dont get what they are asking

Best ResponseYou've already chosen the best response.1well, we're basically doing the same thing that we've been doing so far, except with letters (variables) instead of numbers so, if our first point is (0,0) and our second point is (m,n), we follow the same procedure we add the xcoordinates together and divide by 2, getting...?

Best ResponseYou've already chosen the best response.1not quite... the xcoordinates are 0 and m, correct? so when we take the average we get (0+m)/2 = m/2, with me so far?

Best ResponseYou've already chosen the best response.1using the same reasoning for the ycoordinates we get n/2 giving us a final point (m/2,n/2) which is the formula they're looking for

Best ResponseYou've already chosen the best response.0so (m/2,n/2) is the formula? I thought that a midpoint is different than a formula...

Best ResponseYou've already chosen the best response.1well, it's both a midpoint AND a formula, really. a formula is just a set of instructions to find some value, by manipulating known variables what makes it a "formula" is the fact that we can plug in any m and n to get our midpoint so our formula is midpoint = (m/2,n/2)

Best ResponseYou've already chosen the best response.1I'm not sure how detailed of an explanation they want when they say "explain your reasoning"

Best ResponseYou've already chosen the best response.0i think this is the same kind of problem but i would like help. Use the given endpoint R and the midpoint M of RS to find the coordinates of the other endpoint S R(3,0), M(0,5)

Best ResponseYou've already chosen the best response.0R(5,1) M(1,4) R(6,2) M (5,3)

Best ResponseYou've already chosen the best response.1well, the same rule applies, but we have to think a bit differently because we are now given a midpoint + an endpoint, rather than two endpoints.

Best ResponseYou've already chosen the best response.1before, we took the average of the 2 endpoints and got a midpoint, but here we kind of need to work backwards. I'll demonstrate using R(3,0) and M(0,5)

Best ResponseYou've already chosen the best response.1R = endpoint 1 = (3,0) M = midpoint = (0,5) S = endpoint 2 = (x,y) using our rules from before, we know that (3+x)/2 = 0, with me so far?

Vocaloid

Best ResponseYou've already chosen the best response.1so, if (3+x)/2 = 0, what is x = ?

Vocaloid

Best ResponseYou've already chosen the best response.1yup, now let's do y R = endpoint 1 = (3,0) M = midpoint = (0,5) S = endpoint 2 = (x,y) (0+y)/2 = 5, so y = ?

Best ResponseYou've already chosen the best response.1yup, so our point becomes S(3,10) do you think you can try the others now? just follow the template :)
