Question

The speed of an object in space is shown in the graph.






What is the slope of the line?
10
15
20
25

Answer 1

(6-3)/(0.4-0.2)
= 15

the slope of the line = 15
the answer is B.

Answer 2

Answer:

Option B is correct

15

Step-by-step explanation:

Formula for slope is given by:

$\text{Slope} = \frac{y_2-y_1}{x_2-x_1}$

As per the statement:

Form the graph:

Consider two points:

(0.2, 3) and (0.4, 6)

then;

$\text{Slope} = \frac{6-3}{0.4-0.2}$

⇒$\text{Slope} = \frac{3}{0.2}$

⇒$\text{Slope}= 15$

Therefore, the slope of the line is, 15
