If (y=(2t-3)x+(t+4)) has (y)-intercept (10), what is the slope?
A. (9)
(t+4=10) से (t=6) मिलता है। ढाल (2t-3=9) है। / From (t+4=10), (t=6). The slope is (2t-3=9).

What are the (y)-intercept and slope in (2x+5y-25=0)?
A. (y)-अवरोध (5), ढाल \(-\frac{2}{5}\)(y)-intercept (5), slope \(-\frac{2}{5}\)
(5y=-2x+25) से \(y=-\frac{2}{5}x+5\) मिलता है। इसलिए (y)-अवरोध (5) और ढाल \(-\frac{2}{5}\) है। / From (5y=-2x+25), \(y=-\frac{2}{5}x+5\). So the (y)-intercept is (5) and slope is \(-\frac{2}{5}\).

If (y=3x+b) and (y=-2x+4) cut the (y)-axis at the same point, what is (b)?
C. (4)
एक ही (y)-अक्ष बिंदु का अर्थ समान (y)-अवरोध है। इसलिए (b=4) है। / The same (y)-axis point means equal (y)-intercepts. Therefore (b=4).

If (y=ax-5) and (y=4x+7) have equal slopes, what is (y) on the first line at (x=2)?
C. (3)
समान ढाल से (a=4) है। (x=2) रखने पर (y=4(2)-5=3) है। / Equal slopes give (a=4). Putting (x=2), (y=4(2)-5=3).

The line (y=-7x+c) has (y)-intercept (3). What will (y) be at (x=-2)?
C. (17)
(y)-अवरोध (3) से (c=3) है। (x=-2) रखने पर (y=-7(-2)+3=17) है। / The (y)-intercept (3) gives (c=3). Putting (x=-2), (y=-7(-2)+3=17).

If the line (y=(k-2)x+5) increases (y) by (28) when (x) increases by (4), what is (k)?
C. (9)
ढाल (k-2) है और (4(k-2)=28)। इससे (k-2=7) और (k=9) मिलता है। / The slope is (k-2) and (4(k-2)=28). Thus (k-2=7) and (k=9).

If the line (y=-(p+1)x+12) decreases (y) by (15) when (x) increases by (3), what is (p)?
B. (4)
ढाल (-(p+1)) है और कमी (3(p+1)=15) होगी। इसलिए (p+1=5) और (p=4) है। / The slope is (-(p+1)), and the decrease is (3(p+1)=15). So (p+1=5) and (p=4).

In (3y-2x=12), what are the value of (y) at (x=0) and the slope?
A. (y=4), ढाल \(\frac{2}{3}\)(y=4), slope \(\frac{2}{3}\)
(3y=2x+12) से \(y=\frac{2}{3}x+4\) मिलता है। इसलिए (x=0) पर (y=4) और ढाल \(\frac{2}{3}\) है। / From (3y=2x+12), \(y=\frac{2}{3}x+4\). So at (x=0), (y=4) and the slope is \(\frac{2}{3}\).

If (m+c=10) and (c=4) in (y=mx+c), what is the slope?
C. (6)
(c=4) रखने पर (m+4=10) मिलता है। इसलिए (m=6), जो ढाल है। / Putting (c=4) gives (m+4=10). Therefore (m=6), which is the slope.

If the slope is (-3) and (m+c=5) in (y=mx+c), what is the (y)-intercept?
C. (8)
ढाल (-3) से (m=-3) है। (-3+c=5) से (c=8), जो (y)-अवरोध है। / Slope (-3) gives (m=-3). From (-3+c=5), (c=8), which is the (y)-intercept.
