In the line (y=7x+2), how much will (y) increase when (x) increases by (5)?
B. (35)
ढाल (7) है। (x) में (5) की वृद्धि से (y) \(7\times5=35\) बढ़ेगा। / The slope is (7). An increase of (5) in (x) makes (y) increase by \(7\times5=35\).

In the line (y=-4x+19), what change will occur in (y) when (x) increases by (6)?
C. (24) घटेगाDecreases by (24)
ढाल (-4) है। परिवर्तन \(-4\times6=-24\) है इसलिए (y) (24) घटेगा। / The slope is (-4). The change is \(-4\times6=-24\), so (y) decreases by (24).

What are the slope and (y)-intercept in the equation (7y=-21x+28)?
B. ढाल (-3) और (y)-अवरोध (4)Slope (-3) and (y)-intercept (4)
(7) से भाग देने पर (y=-3x+4) मिलता है। इसलिए ढाल (-3) और (y)-अवरोध (4) है। / Dividing by (7) gives (y=-3x+4). So the slope is (-3) and the (y)-intercept is (4).

What is the (y)-intercept of the equation (3x+4y=20)?
C. (5)
(x=0) रखने पर (4y=20) और (y=5) मिलता है। इसलिए (y)-अवरोध (5) है। / Putting (x=0) gives (4y=20) and (y=5). Therefore the (y)-intercept is (5).

What is the slope of the equation (6x+3y=21)?
B. (-2)
(3y=-6x+21) और (y=-2x+7) है। इसलिए ढाल (-2) है। / (3y=-6x+21) and (y=-2x+7). Therefore the slope is (-2).

In the line \(y=\frac{7}{3}x-4\), how much will (y) increase when (x) increases by (3)?
B. (7)
ढाल \(\frac{7}{3}\) है। परिवर्तन \(\frac{7}{3}\times3=7\) होगा। / The slope is \(\frac{7}{3}\). The change will be \(\frac{7}{3}\times3=7\).

In the line \(y=-\frac{5}{6}x+11\), how much will (y) decrease when (x) increases by (12)?
C. (10)
ढाल \(-\frac{5}{6}\) है। परिवर्तन \(-\frac{5}{6}\times12=-10\) है इसलिए कमी (10) है। / The slope is \(-\frac{5}{6}\). The change is \(-\frac{5}{6}\times12=-10\), so the decrease is (10).

If (y=mx+3) passes through ( (4,23) ), what will (m) be?
B. (5)
बिंदु रखने पर (23=4m+3) मिलता है। इससे (4m=20) और (m=5) है। / Substituting the point gives (23=4m+3). Thus (4m=20) and (m=5).

If a line has slope (4) and cuts the (y)-axis at ( (0,-7) ), what is its equation?
A. (y=4x-7)
ढाल (4) है और (y)-अवरोध (-7) है। इसलिए (y=4x-7) है। / The slope is (4) and the (y)-intercept is (-7). Therefore (y=4x-7).
