A hang glider begins his trip at 400 feet above sea level. H e decends at a rate of 40 feet per minute minute Write an equation in slope-intercept form for the change in elevation.
Y= -40x + 400 This is correct bcuz you are descending 40 feet per minute. So the 40 is your slope and it is negative. You add 400 because that’s where the glider is starting at.
