Pls help!!

Since P, Q, R and S divide the line segments joining A(2,5) and B(7,-5) in 5 equal parts, so, 

 

AP:PB = 1:4

AQ: QB = 2:3

AR:RB = 3:2

AS : SB = 4:1

 

(To understand better how I arrived at these ratios, just draw a line AB and cut it into 5 equal parts using P, Q, R and S and now, if you will see the ratios of the length, you should come at the same ratios as above)

Using the section formula,
