Question 1/5
Expert Mathematics
Pair of Linear Equations in Two Variables Graphical method of finding solutions. Class 10 Level 54
रेखा (13x+4y=52) खींचने के लिए कौन सा बिंदु गलत चुना गया है?
Which point is chosen incorrectly for drawing the line (13x+4y=52)?
#graphical method
#point verification
#plotting error
#line graph
A ((4,0))
B ((0,13))
C (\left\(\frac{8}{13},11\right\))
D ((2,8))
Explanation opens after your attempt
Correct Answer
D. ((2,8))
Step 1
Concept
Substituting ((2,8)) gives \(13\cdot2+4\cdot8=58\), not (52). Check every point in the equation before drawing the graph.
Step 2
Why this answer is correct
The correct answer is D. ((2,8)). Substituting ((2,8)) gives \(13\cdot2+4\cdot8=58\), not (52). Check every point in the equation before drawing the graph.
Step 3
Exam Tip
((2,8)) रखने पर \(13\cdot2+4\cdot8=58\), जो (52) नहीं है। ग्राफ बनाने से पहले हर बिंदु को समीकरण में जांचें।

रेखा (5x+11y=55) के लिए कौन सा बिंदु रेखा पर नहीं है?
Which point does not lie on the line (5x+11y=55)?
#graphical method
#point on line
#plotting error
#verification
A ((11,0))
B ((0,5))
C (\left\(\frac{22}{5},3\right\))
D ((4,3))
Explanation opens after your attempt
Correct Answer
D. ((4,3))
Step 1
Concept
Substituting ((4,3)) gives (20+33=53), not (55). A wrong point can make the graph show a wrong line.
Step 2
Why this answer is correct
The correct answer is D. ((4,3)). Substituting ((4,3)) gives (20+33=53), not (55). A wrong point can make the graph show a wrong line.
Step 3
Exam Tip
((4,3)) रखने पर (20+33=53), जो (55) नहीं है। गलत बिंदु से ग्राफ गलत रेखा दिखा सकता है।

रेखा (4x-9y=36) खींचने के लिए कौन सा बिंदु गलत चुना गया है?
Which point is chosen incorrectly for drawing the line (4x-9y=36)?
#graphical method
#point verification
#plotting error
#line graph
A ((9,0))
B ((0,-4))
C ((18,4))
D ((0,4))
Explanation opens after your attempt
Correct Answer
D. ((0,4))
Step 1
Concept
Substituting ((0,4)) gives \(4\cdot0-9\cdot4=-36\), not (36). Check every point in the equation before drawing the graph.
Step 2
Why this answer is correct
The correct answer is D. ((0,4)). Substituting ((0,4)) gives \(4\cdot0-9\cdot4=-36\), not (36). Check every point in the equation before drawing the graph.
Step 3
Exam Tip
((0,4)) रखने पर \(4\cdot0-9\cdot4=-36\), जो (36) नहीं है। ग्राफ बनाने से पहले हर बिंदु को समीकरण में जांचें।

रेखा (3x+8y=24) के लिए कौन सा बिंदु रेखा पर नहीं है?
Which point does not lie on the line (3x+8y=24)?
#graphical method
#point on line
#plotting error
#verification
A ((8,0))
B ((0,3))
C (\left\(\frac{8}{3},2\right\))
D ((4,2))
Explanation opens after your attempt
Correct Answer
D. ((4,2))
Step 1
Concept
Substituting ((4,2)) gives (12+16=28), not (24). A wrong point can make the graph show a wrong line.
Step 2
Why this answer is correct
The correct answer is D. ((4,2)). Substituting ((4,2)) gives (12+16=28), not (24). A wrong point can make the graph show a wrong line.
Step 3
Exam Tip
((4,2)) रखने पर (12+16=28), जो (24) नहीं है। गलत बिंदु से ग्राफ गलत रेखा दिखा सकता है।

रेखा (2x+7y=14) के लिए कौन सा बिंदु रेखा पर नहीं है?
Which point does not lie on the line (2x+7y=14)?
#graphical method
#point on line
#plotting error
#verification
A ((7,0))
B ((0,2))
C (\left\(\frac{7}{2},1\right\))
D ((1,2))
Explanation opens after your attempt
Correct Answer
D. ((1,2))
Step 1
Concept
Substituting ((1,2)) gives (2+14=16), not (14). Taking a wrong point makes the graph wrong.
Step 2
Why this answer is correct
The correct answer is D. ((1,2)). Substituting ((1,2)) gives (2+14=16), not (14). Taking a wrong point makes the graph wrong.
Step 3
Exam Tip
((1,2)) रखने पर (2+14=16), जो (14) नहीं है। ग्राफ में गलत बिंदु लेने से रेखा गलत बनती है।
