fixed the problem becaise i submitted it wrongf beforehand

The point P(1/2,10) lies on the curve y=5x.

If  is the point (x,5/x), find the slope of the secant line PQ for the values below of .If x=0.6, the slope of PQ is:   and if x=0.51, the slope of PQ is:   and if x=0.4, the slope of PQ is:   and if x=0.49, the slope of PQ is:   

Based on the results, guess the slope of the tangent line to the curve at P(0.5,10).

y = 5x is not a curve It is a straight line. As such it does not have a secant.

Also (1/2,10) is not on the "curve" y=5x.
