Question

the midpoint of UV is (5,-11) the coordinates for one endpoint are U(3,5) find the coordinates for point V

or if you can't take that further, graph it out and extend the line

Answer 3

slope is not asked for ...

Answer 4

@adamaero they didnt ask for the slope all it asks is to find the coordinates for the other endpoint

Answer 5

@amistre64 what do you mean?

Answer 6

if something is halfway between 2 things, then the distance to each thing is the same. right?

so, start at the starting point, see how far it takes you to get to the middle, then add that much to get to the other end ....

Answer 7

we have starting points:

3

and

5

Answer 8

we have middle points

3 ...... 5

and

5 ...... -11

we can determine what it took to get there to add on to the end and get to the end points

Answer 9

@amistre64 i get that but i dont understand how to find the other endpoint....would it be 2 and 15?

Answer 10

3 (+2) 5 (+2) _____

5 (-17) -11 (-17) _____

if you 'get it' then you understand how to find them

Answer 11

-16, not -17 ... fat fingers annd all lol
