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

Answer: B. negative

Step-by-step explanation:

Given: In a linear equation, the independent variable increases at a constant rate while the dependent variable decreases at a constant rate.

We know that the slope of a line is given by :-

$k=\dfrac{\text{change in y}}{\text{change in x}}$

According to the given information, if independent variable increases at a constant rate while the dependent variable decreases at a constant rate, then the slope of line will be :-

$k=\dfrac{\text{Negative}}{\text{Positive}}=\text{Negative}$

Hence, the slope of line = Negative.

Answer 2

The best and most correct answer among the choices provided by your question is the second choice or letter B.

The slope of this line is NEGATIVE.
