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

Option B is correct

15

Explanation:

Formula for slope is given by:

`\text{Slope} = (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} = (6-3)/(0.4-0.2)`

⇒
`\text{Slope} = (3)/(0.2)`

⇒
`\text{Slope}= 15`

Therefore, the slope of the line is, 15
