Answer:

The correct option is B.

Step-by-step explanation:

The slope of a line is calculated as

$m=\frac{y_2-y_1}{x_2-x_1}$

The slope of line is undefined if there is no change in the values of x. It is possible only in the case of vertical line.

Graph B represents a vertical line. So the slope of the line in graph B is

$m_B=\infty$

The slope of line B is undefined, therefore the correct option is B.

UNO [17]

Answer:

Step-by-step explanation:

First, simplify by finding the absolute values:

2|-9| - |-2|

2(9) - (2)

Then, simplify this by multiplying 2 and 9:

18 - 2

= 16

So, the answer is 16

Use the law of sines to find the value of w.

Lunna [17]

Option B: 4.0 cm is the value of w

Explanation:

It is given that $\angle W= 39$ , $\angle U=31$ , $VW=3.3$ and $UV=w$

Using the law of sines, we have,

$\frac{sin U}{3.3} =\frac{sin W}{w}$

Substituting the values, we have,

$\frac{\sin 31}{3.3}=\frac{\sin 39}{w}$

Cross multiplying, we get,

$(sin31) w=3.3( \sin 39)$

Simplifying, we have,

$0.515w=2.077$

Dividing both sides by 0.515, we have,

$w=4.0$

Thus, the value of w is 4.0 cm

Hence, Option B is the correct answer.
