रेखीय क्षय में ग्राफ सामान्यतः किस दिशा में जाता है?
In linear decay, in which direction does the graph generally go?
#linear_decay
#graph_direction
#negative_rate
A बाएं से दाएं ऊपर / Upward from left to right
B बाएं से दाएं नीचे / Downward from left to right
C सदैव ऊपर की ओर वक्र / Always upward curve
D सदैव स्थिर / Always constant
Explanation opens after your attempt
Correct Answer
B. बाएं से दाएं नीचे / Downward from left to right
Step 1
Concept
With a negative rate, the value decreases. So the line goes downward from left to right.
Step 2
Why this answer is correct
The correct answer is B. बाएं से दाएं नीचे / Downward from left to right. With a negative rate, the value decreases. So the line goes downward from left to right.
Step 3
Exam Tip
ऋणात्मक दर होने पर मान घटता है। इसलिए रेखा बाएं से दाएं नीचे जाती है।

कौन सा नियम रेखीय क्षय को दिखाता है?
Which rule represents linear decay?
#linear_decay
#identify_rule
#negative_rate
A (y=18+4x)
B (y=20)
C (y=25-3x)
D \(y=x^2-3\)
Explanation opens after your attempt
