If line b is perpendicular to line a, and line c is perpendicular to line a, what is the slope of line c?

1

Step-by-step explanation:

Slope of line a=-1

c is perpendicular to a, so slope is negative reciprocal of a, or -1*(-1/1)=1

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

answer: idk
