Answer:

The correct option is A.

Step-by-step explanation:

A real number is called a rational number if it can be represented as p/q, where p and q are two integers and q≠0. For example: 2,4/5, 0.2.

A real number is called an irrational number if it can not be represented as p/q, where p and q are two integers and q≠0. For example: π, √2, 2.333....

In option A, all numbers are irrational numbers.

Therefore option A is correct.

In option B,

\sqrt{9}=3

3 is a rational numbers, so √9 is a rational number.

Therefore option B is incorrect.

In option C,

\sqrt{144}=12

12 is a rational numbers, so √144 is a rational number.

Therefore option C is incorrect.

In option D,

\sqrt{121}=11

11 is a rational numbers, so √121 is a rational number.

Therefore option D is incorrect.

Y=-3x+4
Gradient, m= -3
Parallel lines have equal gradients;
So, equation II,
y=mx+c
y=-3x+c
Replacing for x and y using point (-4, 6)
6=-3(-4)+c
6=12+c
6-12=c
