y=a%2Alog%28%28x%29%29%2Bb
0.6086271206+=a%2Alog%2810%29%2Bb
1.0.6086271206+=a%2Bb
.
.
0.9744801206+=a%2Alog%28100%29%2Bb
2.0.9744801206+=2a%2Bb
Subtract eq. 1 from eq. 2,
2a%2Bb-a-b=0.9744801206-0.6086271206
a=+0.365853
Then from eq. 1,
0.6086271206+=0.365853%2Bb
b=0.242774
.
.
.
y=+0.365853%2Alog%28%28x%29%29%2B0.242774
