The initial value is $12 (entrance fee) and the rate of change is $2 per ride ticket. So, b=12 and m=2.

Determine the initial value and the rate of change in the following description. A 2,000-gallon tank is half full with 1,000 gallons of water. Water is being pumped into the tank at a rate of 15 gallons per minute.(1 point)

The initial value is 1000 gallons (half full) and the rate of change is 15 gallons per minute. So, b=1000 and m=15.

To find the rate of change, we need to calculate the difference in y-values divided by the difference in x-values:

Rate of change (m) = (change in y) / (change in x)

For this table:
Change in y = 8 - 4 = 4
Change in x = -3 - 1 = -4

Rate of change (m) = 4 / -4 = -1

To find the initial value (y-intercept or b), we can choose any point from the table and use the slope (rate of change) we found.

Let's use the point (1, 4):
y = mx + b
4 = -1(1) + b
4 = -1 + b
b = 4 + 1
b = 5

Therefore, the rate of change is m = -1 and the initial value is b = 5.

To determine the initial value and rate of change of the linear function from the graph, we can use the two points (0, 0) and (2, 3).

The rate of change (slope) can be calculated as:
Rate of change (m) = (change in y) / (change in x)
m = (3 - 0) / (2 - 0)
m = 3/2
m = 1.5

The initial value (y-intercept or b) can be found by substituting one of the points and the slope into the slope-intercept form equation y = mx + b.
Let's use the point (0, 0):
0 = 1.5(0) + b
b = 0

Therefore, the initial value is 0, and the rate of change (slope) is 1.5.

To determine the initial value and rate of change of the linear function from the graph, we can use the points (-3, 2.5), (0, 1), and (2, 0).

The rate of change (slope) can be calculated using any two distinct points:
For example, let's calculate the rate of change using the points (-3, 2.5) and (0, 1):
m = (1 - 2.5) / (0 - (-3))
m = -1.5 / 3
m = -0.5

Therefore, the rate of change (slope) is -0.5.

To find the initial value (y-intercept or b), we can choose any point and substitute the slope into the slope-intercept form equation y = mx + b. Let's use the point (0, 1):
1 = -0.5(0) + b
b = 1

Therefore, the initial value is 1, and the rate of change (slope) is -0.5.
