What is the value of p such that the line passing through (9,-1) and (6,p) has a slope of -1?

p=-4

Step-by-step explanation:

slope= rise/run

(-1-p)/(6-9)=-1

(-1-p)/(-3)=-1

-1-p=3

-p=4

p=-4

the mistake in the pattern is that :

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
