Which of the following is true about the expression given below? 9> 2 a.9 is to the left of 2 on a horizontal number line. b.9 is the opposite of 2 on a horizontal number line. c.9 is to the right of 2 on a horizontal number line. d.9 is at the same place as 2 on a horizontal number line.

Option 'C' is correct.

Step-by-step explanation:

Since we have given that

9 > 2

i.e. 9 is to the right of 2 on a horizontal number line

As we know that in the Cartesian plane, upper most is for y- positive coordinate, lower most is for y- negative coordinate

Similarly, right most is for x-positive coordinate and left most is for x- negative coordinate.

And we have 9>2

Both 2 and 9 are positive numbers so, both numbers must be in the right part of axis.

And 9 is always right of 2 on a horizontal number line.

Hence, Option 'C' is correct.

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:
