Question

If the coordinates of the points p and q are (4,-3) and (-1,7), then find abscissa of a point r on the line segment pq such that pr/pq=3/5

Answer 1

As PR/PQ = 3/5,
therefore it can be written like this
PR:PQ = 3:5
PR = 3 and PQ = 5
Therefore QR = PQ - PR
QR = 5-3 = 2
Now, the Ratio of PQ:QR = 3:2
Line Segment,
P---------3----------R-------2------Q
p_____3_______r_____2____q
Therefore, m1:m2 = 3:2
Now Apply Section Formula and finish off the Problem...
