Answer:
C- Negative Slope
This is because it you stated it is decreasing and it is proportional.
Negative slope best describes a condition in which a quantity decreases at a rate that is proportional to the current value of the quantity .
What is slope?
The slope of a line is the measure of the steepness and the direction of the line. Finding the slope of lines in a coordinate plane can help in predicting whether the lines are parallel, perpendicular, or none without actually using a compass.
What are types of slope?
Depending upon the relationship between the two variables x and y and thus the value of the gradient or slope of the line obtained.
There are 4 different types of slopes, given as,
- Positive slope: indicates that while moving from left to right in the coordinate plane, the line rises, which also signifies that when x increases, so do y.
- Negative slope : indicates that while moving from left to right in the coordinate plane, the line falls, which also signifies that when x increases, y decreases.
- Zero slope : the rise is zero, and thus applying the rise over run formula we get the slope of the line as zero.
- Undefined Slope: The slope of a vertical line is undefined.
According to the question
A quantity decreases at a rate that is proportional to the current value of the quantity
As,
Slope decreases i.e when x increases, y decreases.
and the rate at which it is decreasing is proportional to the current value of the quantity .
Therefore ,
It best describes the negative slope .
Hence, the Negative slope best describes a condition in which a quantity decreases at a rate that is proportional to the current value of the quantity .
