The slope of this graph is - 4
Step-by-step explanation:
The slope of a line is 
, where
and 
are two points on the line- The slope of a horizontal line is zero
- The slope of a vertical line is undefined
∵ The graph is a line
∵ The line passes through points (1 , -2) and (0 , 2)
∴ 
= 1 and 
= 0
∴ 
= -2 and 
= 2
- Substitute these values in the rule below
∵ 
∴ 
∴ m = - 4
The slope of this graph is - 4

Answer:
sorry I don't knowledge can see the your brother's do
If the troops hike 7km/2hr (read 7 kilometers per 2 hours), then to find how far they'd hike 4hr, just find multiply the top and bottom by 2. We do this because we found that to get from 2 to 4, we multiply by 2. And since this is a rate, we multiply the top by this value as well, so 7x2=14km
