Find Gradient
**Find solutions to the equation 4x + 60/x = 40 by drawing a suitable line.
My attempted solution:
Graph drawn,
Gradient = 10
** i have solved the question ' Find solutions to the equation 4x + 60/x = 40 by drawing a suitable line.' by other means but i just do not know where to draw a straight line at. how does this relate to y = 3x + 60/x - 35 ??
please help...
kind regards
