Air pressure decreases exponentially with increases in elevation. The air pressure, y, (in atm units) at a given elevation, x, (in meters) can be modeled using the equation y = e ^ -kx , where k is the decay constant. At an elevation of 5486 m where the air pressure is 0.5 atm what is the value of k?

Any is very appreciated! (picture is provided below)not sure how to do this at all won't lie
