Answer:
1) (B)
2) (D)
3) (D)
Explanation:
1) 3x+9y=18
when x = 0, y = 2
When y=0, x= 6,
Then line which shows the graph is (B).
2) After plotting the points in XY-plane, we get a straight line.
Equation of line : y = -x-2
Standard form of equation: y = mx+c, where m is the slope
Therefore, slope = -1
(D) is correct.
3) Comparing two graphs we get that Each point is translated left 4 units.
Option(D) is correct.
4) Let the number be x. Then, according to question,
-2 = 10
= 12
x = 16
Therefore, the required number is 16.
Option (D) is correct.
