To create a table of values from the graph, we need to look at the x and y coordinates at different points on the graph.
x | y
-------------
0 | 10
5 | 8
10 | 6
15 | 4
20 | 2
When x = 20, the value of y is 2.
Three more pairs of values could be:
x | y
-------------
25 | 0
30 | -2
35 | -4
A situation that could be modeled using this graph could be the time taken (x-axis) versus the temperature decrease (y-axis) as an ice block melts. Initially, the temperature decreases at a faster rate, but it slows down over time until the ice block completely melts (y = 0).
Create a table of values from the graph. Then find the value of y when x=20. Use pencil and paper. Find three more pairs of values. Then write a situation you could model using this graph
