1.points A,B,C are collinear such that AB= BC=10. the coordinate of A is 2. find the coordinates of B and C if the coordinate of B is greater than A. 2. Points

Question

 

how to get the measurement of  line segment?

Answer 1

REMEMBER THAT COLLINEAR MEANS 'ON THE SAME LINE'

I ASSUME THAT YOU MEAN A = 2.

 

a__________________________b___________________________c

if ab = bc = 10 then ab = 10 and bc = 10 so ac = 20

B WOULD BE 10  UNITS AWAY FROM A. So we can consider the coordinate pair for b is (12,0) or that b is at 12 (on the x axis).

Similarly c would be 20 units away from  a  so c would be at (22,0) on the x axis.

I'm not sure I understand your question completely.
