    Find Secant Line

    If the point P(4,2) likes on the curve y=radical x. If Q is the point (x,radicalx), use you calculator for find the slope of the secant line PQ for the value x=3.99

    What do I do?

    Hello, ToXic01!

    \text{The point }P(4,2)\text{ lies on the curve }y\:=\:\sqrt{x}

    \text{If }Q\text{ is the point }(x,\sqrt{x})\text{, use your calculator to find}

    \text{the slope of the secant line }PQ\text{ for the value }x=3.99

    Did you read the problem at all?

    You are asked to fnd the slope of the line through P(4,2) and Q(3.99,\sqrt{3.99})

    How hard is that?
