What are the slope and (y)-intercept in the equation (4y=8x-28)?
C. ढाल (2), (y)-अवरोध (-7)Slope (2), (y)-intercept (-7)
(4) से भाग देने पर (y=2x-7) मिलता है। इसलिए ढाल (2) और (y)-अवरोध (-7) है। / Dividing by (4) gives (y=2x-7). So the slope is (2) and the (y)-intercept is (-7).

What is the slope of the equation (7x+2y=10)?
D. \( -\frac{7}{2} \)
(2y=-7x+10) से \(y=-\frac{7}{2}x+5\) मिलता है। इसलिए ढाल \(-\frac{7}{2}\) है। / From (2y=-7x+10), \(y=-\frac{7}{2}x+5\). Therefore the slope is \(-\frac{7}{2}\).

What is the (y)-intercept of the equation (5x-3y=12)?
A. ( -4 )
(x=0) रखने पर (-3y=12) और (y=-4) मिलता है। इसलिए (y)-अवरोध (-4) है। / Putting (x=0) gives (-3y=12) and (y=-4). Therefore the (y)-intercept is (-4).

The line (y=-2x+c) passes through ( (6,-1) ). What is its (y)-intercept?
C. (11)
बिंदु रखने पर (-1=-2(6)+c) मिलता है। इसलिए (c=11), जो (y)-अवरोध है। / Substituting the point gives (-1=-2(6)+c). Therefore (c=11), the (y)-intercept.

The line (y=mx+9) passes through ( (-2,3) ). What is its slope?
A. (3)
बिंदु रखने पर (3=-2m+9) मिलता है। इससे (-2m=-6) और (m=3) है। / Substituting the point gives (3=-2m+9). Thus (-2m=-6) and (m=3).

If (2y=(a-4)x+16) has slope (3), what will (a) be?
B. (10)
\(y=\frac{a-4}{2}x+8\) होगा, इसलिए ढाल \(\frac{a-4}{2}\) है। \(\frac{a-4}{2}=3\) से (a=10) मिलता है। / \(y=\frac{a-4}{2}x+8\), so the slope is \(\frac{a-4}{2}\). From \(\frac{a-4}{2}=3\), (a=10).

If (ky=15x-30) has (y)-intercept (-6), what is (k)?
C. (5)
\(y=\frac{15}{k}x-\frac{30}{k}\) होगा। \(-\frac{30}{k}=-6\) से (k=5) मिलता है। / \(y=\frac{15}{k}x-\frac{30}{k}\). From \(-\frac{30}{k}=-6\), (k=5).
