In the diagram, the straight line SP is drawn having S and P as its x- and y-intercepts respectively. The equation of SP is x + ap-a-0, a > 0. It is also given that OS-30P. The straight line RT is drawn with R on SP and RT J. PS. RT cuts the p-axis in T(0:-5323). 4.1) 0 4.1 Calculate the coordinates of P. (2)​
