The line (y=6x+b) has (y)-intercept (13). Which equation is correct?
C. (y=6x+13)
(b) (y)-अवरोध है। (b=13) रखने पर (y=6x+13) बनता है। / (b) is the (y)-intercept. Putting (b=13) gives (y=6x+13).

How are the two lines (y=-4x+6) and (y=-4x-9) related?
A. उनकी ढाल समान हैTheir slopes are the same
दोनों में (x) का गुणांक (-4) है। स्थिर पद अलग हैं इसलिए (y)-अवरोध अलग होंगे। / Both have coefficient (-4) of (x). Their constant terms are different, so their (y)-intercepts are different.

What similarity do the two lines (y=3x-8) and (y=-9x-8) have?
B. दोनों का (y)-अवरोध समान हैBoth have the same (y)-intercept
दोनों में स्थिर पद (-8) है। इसलिए दोनों का (y)-अवरोध समान है। / Both have constant term (-8). Therefore both have the same (y)-intercept.

What are the slope and (y)-intercept of the line (y=-18)?
B. ढाल (0) और (y)-अवरोध (-18)Slope (0) and (y)-intercept (-18)
(y=-18) क्षैतिज रेखा है। इसकी ढाल (0) और (y)-अवरोध (-18) है। / (y=-18) is a horizontal line. Its slope is (0) and its (y)-intercept is (-18).

In the line (y=0x+9), what change will occur in (y) when (x) increases by (12)?
A. (0)
ढाल (0) है। इसलिए (x) बदलने पर भी (y) में कोई परिवर्तन नहीं होगा। / The slope is (0). So even when (x) changes, there is no change in (y).

In the line \(y=\frac{3}{4}x+2\), how much will (y) increase when (x) increases by (8)?
B. (6)
ढाल \(\frac{3}{4}\) है। परिवर्तन \(\frac{3}{4}\times8=6\) होगा। / The slope is \(\frac{3}{4}\). The change will be \(\frac{3}{4}\times8=6\).

In the line \(y=-\frac{2}{7}x+15\), how much will (y) decrease when (x) increases by (21)?
C. (6)
ढाल \(-\frac{2}{7}\) है। परिवर्तन \(-\frac{2}{7}\times21=-6\) है इसलिए कमी (6) है। / The slope is \(-\frac{2}{7}\). The change is \(-\frac{2}{7}\times21=-6\), so the decrease is (6).

If the line (y=mx-6) passes through ( (3,9) ), what is the slope?
C. (5)
बिंदु रखने पर (9=3m-6) मिलता है। इससे (3m=15) और (m=5) है। / Substituting the point gives (9=3m-6). Thus (3m=15) and (m=5).

If the line (y=4x+c) passes through ( (5,11) ), what is the (y)-intercept?
B. (-9)
बिंदु रखने पर (11=4(5)+c) मिलता है। इसलिए (c=-9) (y)-अवरोध है। / Substituting the point gives (11=4(5)+c). Therefore (c=-9) is the (y)-intercept.

Which line gives (y=15) at (x=0) and has slope (-3)?
B. (y=-3x+15)
(x=0) पर (y=15) से (c=15) मिलता है। ढाल (-3) होने से (y=-3x+15) सही है। / At (x=0), (y=15) gives (c=15). With slope (-3), (y=-3x+15) is correct.
