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

The answer is 15

Explanation:

Answer 2

15

Explanation:

The formula of a slope m :

`m=(y_2-y_1)/(x_2-x_1)`

From the graph we have the points (0.2, 3) and (0.4, 6).

Substitute:

`m=(6-3)/(0.4-0.2)=(3)/(0.2)=(3\cdot10)/(0.2\cdot10)=(30)/(2)=15`
