Answer:
slope is 2
Step-by-step explanation:
first add -14x like...
-14x+7y=-9
+14x +14x
7y=14x-9
divide 7 by the who equation
7y=14x-9
/7
y=2x-9/7
Answer:
The resultant velocity of the airplane is 213.41 m/s.
Step-by-step explanation:
Given that,
Velocity of an airplane in east direction, 
Velocity of wind from the north, 
Let east lies in the direction of the positive x-axis and north in the direction of the positive y-axis.
We need to find the resultant velocity of the airplane. Let v is the resultant velocity. It can be calculated as :


v = 213.41 m/s
So, the resultant velocity of the airplane is 213.41 m/s. Hence, this is the required solution.
