Interpretation of Intercepts
A diver explored the ocean floor 120 feet below the surface and
then ascended at a rate of 30 feet per minute. The graph shows
the diver’s elevation below sea level during the ascent.
1) Write a linear equation for the situation.
2) What does the x-intercept represent in terms of the
problem?
3) What does the y-intercept represent in terms of the problem?
Trish can run the 200 m dash in 25 s. The function f(x) = 200
– 8x gives the distance remaining to run after x seconds.
