Match the y-coordinate with the given x-coordinate for the equation y = log10x. 1. 1/100 -2 2. 1/10 0 3. 1 2 4. 10 1 5. 100 -1

1. log10 (1/100)=log10 (1/10^2)=log10 10^(-2)=(-2) log10 10=(-2)(1)=-2

2. log10 (1/10)=log10 10^(-1)=(-1) log10 10=(-1)(1)=-1

3. log10 (1)=0

4. log10 (10)=1

5. log10 (100)=log10 (10^2)=(2) log10 10=(2)(1)=2
