We have to change the slope in order to have a safe land the plane
The plane is located in (0,-7)
The point on the safe land (14,0)
We can calculate the slope
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Then we substitute
[tex]m=\frac{0+7}{14-0}=\frac{7}{14}=\frac{1}{2}[/tex]
The equation to land safely
[tex]y=\frac{1}{2}x-7[/tex]
ANSWER
y=1/2x-7
