If the line (y=5x+c) passes through ( (3,8) ), what is the (y)-intercept?
B. (-7)
बिंदु रखने पर (8=5(3)+c) मिलता है। इसलिए (c=-7) (y)-अवरोध है। / Substituting the point gives (8=5(3)+c). Therefore (c=-7) is the (y)-intercept.

Which line gives (y=12) at (x=0) and has slope (-4)?
B. (y=-4x+12)
(x=0) पर (y=12) से (c=12) मिलता है। ढाल (-4) होने से (y=-4x+12) सही है। / At (x=0), (y=12) gives (c=12). With slope (-4), (y=-4x+12) is correct.

Which line gives (y=-8) at (x=0) and has slope (6)?
A. (y=6x-8)
(x=0) पर (y=-8) का अर्थ (c=-8) है। ढाल (6) से रेखा (y=6x-8) है। / (y=-8) at (x=0) means (c=-8). With slope (6), the line is (y=6x-8).

Which statement about (y=9x+2) and (y=-9x+2) is correct?
B. ढाल अलग है और (y)-अवरोध समान हैंSlopes are different and (y)-intercepts are same
ढालें (9) और (-9) हैं लेकिन स्थिर पद (2) समान है। इसलिए (y)-अवरोध समान हैं। / The slopes are (9) and (-9), but the constant term (2) is the same. So the (y)-intercepts are the same.

Which statement about (y=-2x+10) and (y=-2x-3) is correct?
A. ढाल समान है और (y)-अवरोध अलग हैंSlopes are same and (y)-intercepts are different
दोनों में (x) का गुणांक (-2) है। स्थिर पद (10) और (-3) अलग हैं। / Both have coefficient (-2) of (x). The constant terms (10) and (-3) are different.

What are the signs of the slope and the (y)-intercept in the line (y=11x-4)?
A. ढाल धनात्मक और (y)-अवरोध ऋणात्मकSlope positive and (y)-intercept negative
ढाल (11) है जो धनात्मक है और स्थिर पद (-4) ऋणात्मक है। संकेत अलग-अलग देखें। / The slope is (11), which is positive, and the constant term (-4) is negative. Check the signs separately.
