Question

In a linear equation, the independent variable increases at a constant rate while the dependent variable decreases at a constant rate. The slope of this line is
A. zero
B. negative
C. positive
D. undefined

Answer 1

B. Negative

The y variable is the dependent variable, the x variable is the independent variable (you plug in values of x to get your y).
Given, the independent "x" change is increasing (or +) and the dependent "y" change is decreasing (-),
your slope is: ( - )/ ( + ) = ( - ).
