Asea lion dove from the water's surface at sea level to an altitude of −216.12 meters in 2.4 minutes.
what is the average change in the sea lion's altitude per minute?
enter your answer in the box.

The average change in the sea lion's altitude is -90.05 m/min.

Step-by-step explanation:

We have been given the altitude as −216.12 meters and the time taken in 2.4 minutes.

The average change in the sea lion's altitude is given by

On substituting the known values, we get

Therefore, the average change in the sea lion's altitude is -90.05 m/min.

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2

horizontal translation of 2 units in the positive x direction

vertical translation of 3 units in the positive y direction
