2. Equations a. Write a linear equation for each of the three health clubs to represent the total cost of
the club membership, y, in terms of the length of time being a member at the club in
months, x. Use the form y=mx+b
Club A:
Club B:
Club C:
Explain the meaning of the slope and y-intercept for each club.

The path traveled by a bottlenose dolphin as it jumps out of water is modeled by the equation y=-0.4+3x, where t is the height above water and x is the horizontal distance in feet. if a beam of light is shone upward at an angle modeled by the equation x+y=10, at what height from the waters surface will the beam of light hit the dolphin
