Question

Mr. Mole's burrow lies 5 meters below the ground. He started digging his way deeper into the ground, descending 3 meters each minute. Graph the relationship between Mr. Mole's elevation relative to the ground (in meters) and time (in minutes).
coordinates please!

Answer 1

Answer:

See the graph attached

Step-by-step explanation:

Every minute = 3m

At time zero, the depth is zero

Giving coordinates of (0, 0)

At time 1 minute, the depth is 3m

Giving coordinates of (1, 3)

This gives a linear equation

Slope = Δy/Δx

= (3-0)/(1-0)

= 3/1

= 3

Take any general point (x, y)

The equation of the line is:

(y-0)/(x-0) = 3

y/x = 3

y = 3x

See the plot which goes up to a depth of 5m
