Speed of the plane in still air: .
Windspeed: .
Assume that is the speed of the plane in still air, and that is the speed of the wind.
The question states that when going against the wind (,) the plane travels in . Hence, .
Similarly, since the plane travels in when travelling in the same direction as the wind (,) .
Add the two equations to eliminate . Subtract the second equation from the first to eliminate . Solve this system of equations for and : and .
Hence, the speed of this plane in still air would be , whereas the speed of the wind would be .
Yes the y-intercept is -1 so True
Yes the rate of change or slope is 2 so True
And Yes the equation is not y=2x+1 it is suppose to be y=2x-1 so False
