/divide by x
then rearange terms
we know that when x = 0 then y = 0.5
that gives
Likewise plug in the values from (4,-2.5)
and there it is.
you get and solve for q
Given x and y are related by the equation xy=px+q/x where p and q are constant.A straight line graph is obtained by plotting y against 1/(x^2),it passes through the points (0,0.5) and (4,-2.5).calculate the value of p and q.
please help..
