In this item, it is assumed that we are to establish or generate the equation for the temperature of the surrounding x hours after midnight.

From the given above, the slope of the equation should be - 2 since the temperature decreases by this rate. Also, the y-intercept is equal to 60 since this is the initial value. The equation is then,

y = (-2) (1/2) (x) + 60
