Faye281 3 years ago the coordinate of R, the center of PQ is 6 . If the coordinate of P is greater than the coordinate of Q & if RQ=10, what are the coordinates of P & Q ?

1. hoblos

is it coordinate or just the ordinate ? because for coordinate both abscissa and ordinate must be given! and here we have only one number !!

2. Faye281

coordinate

3. hartnn

this question can only be solved by assuming that all 3 points lie on same horizontal(or vertical)axis.....say x-axis in that case the R-->(0,6) RQ=10---->Q=(0,10+6)=(0,16) R centre of PQ----->P=(0,6-10)=(0,-4).... do u have options or something??

4. hartnn

sorry,y-axis is assumed

5. Faye281

what is the coordinates of p and q?

6. hartnn

as i said,if y-axis is assumed,the co-ordinates of P and Q ARE (0,16)and(0,-4) if u only ask for ordinates,its 16 and -4.....

7. hoblos

@hartnn notice that 'P is greater than Q' .. so P is 16 and Q is -4 the abscissa can be other than zero though!! for example they can be P(1,16) and Q(3,-4) if R(2,6) ! so i think it is just the coordinate of P is 16 and that of Q is -4

thank you all ^^

but as u said,coordinates are always pairs! co-ordinate of P is 16 does not make any sense... and if u take any x-co-ordinates like 1,2,3.....RQ=10 will not get satisfied...
