Yep, pick 2 separate numbers for x, sub them in to find y
Use the points you found in part a to find the line
Do you know how to do this?
Using the line from the previous part, pick out the gradient to help find a line that is parallel.
Am i supposed to just pick numbers for this?
Given the function y=(4/x)-6
a) Find two points that satisfy the function
b) Find the equation of the secant line through those two points.
c) Determine if there is a point of tangency where the tangent line is parallel to the secant line in part b). If there are such points, find them or show why such a point does not exist.
