Question

The graph shows the depth below sea level of a pebble falling into a lake. The x-axis shows seconds. The y-axis shows feet below sea level. What is the point on the graph where the y-value is equal to the unit rate of the pebble’s change in elevation in feet per second?

x=0 y=-6

Answer 1
