Answer:
There are 2 different ways, depending on the amount of data given;
<em>1st way:</em> When only the line on the graph is given (Without any coordinate points given) then the slope could be found out with the formula of <u>Rise/Run, or Change in y / Change in x</u>
<em>2nd way: </em>When a line and 2 coordinate points are given, the the formula that would be used is:<u> </u>
<u>, where X₁ and Y₁ are the coordinate points of the 1st given point, and X₂ and Y₂ are the coordinate points of the 2nd given point.</u>

Answer:
63 miles
Step-by-step explanation:
We know that the bear can run at 21 mi/hr. So, multiply 21*3 to get how many miles the bear could run in 3 hrs.

Determine a homogeneous linear differential equation
Rewrite the expression as:
Where
and 
For a homogeneous linear differential equation, the repeated value m is given as:
Substitute values for 
and 
Add 1 to both sides
Square both sides
In complex numbers:
So, the expression becomes:
Add 1 to both sides
This corresponds to the homogeneous linear differential equation
Change the ratio into a fraction
56:80 is the same as 56/80
Divide, make it a decimal
56/80 = 0.7
0.7 = 7/10 or 70/100
70/100 = 70%
70% is your answer

Step-by-step explanation:
Distance = rate × time
If B is the rate of the boat, and C is the rate of the current, then we can write two equations:
18 = (B + C) × 3
18 = (B − C) × 9
Simplifying the equations:
6 = B + C
2 = B − C
Add the equations together to eliminate C:
8 = 2B
B = 4
Plug into either equation to find C:
C = 2
The boat's rate is 4 mph, and the current's rate is 2 mph.
