To determine the initial value of the linear function, we can take any of the given points on the line. Let's use the point (0, 3).
The initial value (or y-intercept) is the y-coordinate of this point, which is 3.
To find the rate of change (slope) of the linear function, we can calculate the difference in y-values divided by the difference in x-values between any two points on the line. Let's use the points (0, 3) and (3, 2).
First, calculate the difference in y-values: 2 - 3 = -1
Then, calculate the difference in x-values: 3 - 0 = 3
So, the rate of change (slope) is -1/3.
Therefore, the initial value is 3 and the rate of change is -0.333 (rounded to three decimal places).
