As a group of hikers climb Mount Hood in Oregon, they notice that the temperature drops 5 degrees for every 1,000-foot increase in elevation. The relationship between the
increase in elevation and decrease in temperature can be modeled by the equation.
5x + 1000y = 0 where x is measured in feet and y is measured in degrees.
Which of the following represents the slope of the equation?
