Answer:
If you are looking for coordinates then its (0,5) (5,-20)
Explanation:
Mr. Mole's burrow lies 5 meters below the ground. This is the same as saying that when Time is 0, Elevation is -5.
Therefore, the graph of the relationship should pass through the point (0,-5)
We are also given the rate of change of the relationship: 3 meters per minute. This means that when Time increases by 1, Elevation decreases by 3.
Therefore, the graph should also pass through the point (0+1,-5-3), which is the point (1,-8) However, this point doesn't appear on the grid! We need to find an equivalent pair of corresponding changes that would help us find a point that we can graph.
Note, for instance, that when Time increases by 5, Elevation decreases by 5x3= 15. Therefore, the graph should pass through the point
(0+5,-5-15)which is the point (5,-20)
Sorry if its confusing :(
