Turn the information into coordinate points.
Point = (time, population)
Point 1 = (1985, 45000)
Point 2 = (2004 , 26000)
Find the slope between these points using the formula
( Slope)—> m = (y2 - y1) / (x2 - x1)
26000-45000/2004-1985=-19000/19= -1000
Average rate of change is decrease of 1000 sea lion per year

Answer:
<u>k = 220</u>
Step-by-step explanation:
<u>Proportion of y and x</u>
<u>Given</u> :
<u>Solving</u> :
- 55 = k/4
- k = 55 x 4
- <u>k = 220</u>
Answer:

Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:

In which m is the slope and b is the y-intercept(value of y when x = 0).
If two lines are perpendicular, the multiplication of their slopes is -1.
Contains (0, 2)
This means that
. So

Finding the slope:
Perpendicular to y = 2/3x + 1 means that:



So
