SOLUTION: Find the slope of the tangent line at the given point then write the equation of the tangent line.
f(x)=4/x, x=5
Ans y=-4x/25+8/5
I keep getting this answer 4x + 25y = 40

Find the slope (dy/dx) at x = 5
and at x = 5,
, so...
Substitute x = 5 and y = 4/5
Solve for b. Add to both sides.
so finally...
