1/8 = 0.125
3/20 = 0.150
Therefore 1/8 < 3/20
1) Find the derivative

and

.
2) The equation of the tangent line is

, so at point (2,6):

and


-the equation of the tangent line at point (2,6).
The equation for finding slope is y2-y1 over x2-x1.
8-2=6
-6-4=-10
The slope is 6/-10
They’re similar bc all sides have the same scale factor
