Helen is swimming in a lake when she decides she wants her goggles. To get the goggles she swims at a steady pace back to a floating dock. She starts 52 m from the dock. The graph shows Helen's distance from the dock in relation to the time spent swimming back.
Let x represent the time swimming back to the dock. Let y represent the distance from the dock. Which equation is represented by the graph?
Question 5 options:
y = 20x – 52
y = 32x + 52
y = –20x + 52
y = –32x – 52
