The table represents a linear function as for every x value there is only one y value. The graph and the table are attached below. The Elevation is 1127 ft plus 92 times the quantity of the independent variable i.e. hours of climbing. The equation is y=92x+1127

Work Step by Step

The equation of the relationship is y=92x+1127 because when there is no independent variable, the value of the dependent variable is 1127 and then as the number of hours increases by 1, the dependent variable which is elevation increases by 92 ft and so the slope is 92 and the y-intercept is 1127.
