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
