Question

Change one number in the equation below to safely land the plane.

Answer 1

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

$m=\frac{y_2-y_1}{x_2-x_1}$

Then we substitute

$m=\frac{0+7}{14-0}=\frac{7}{14}=\frac{1}{2}$

The equation to land safely

$y=\frac{1}{2}x-7$

ANSWER

y=1/2x-7
