To find the rate of change, we can use the formula:
m = (y2 - y1) / (x2 - x1)
Using the values in the table:
m = (25 - 22) / (8 - 2)
m = 3 / 6
m = 0.5
Therefore, the rate of change is m = 0.5.
To find the initial value, we can use the formula for a linear function:
y = mx + b
Using one of the points in the table (let's use x = 2, y = 22):
22 = 0.5 * 2 + b
22 = 1 + b
b = 21
Therefore, the initial value is b = 21.
m = (y2 - y1) / (x2 - x1)
Using the values in the table:
m = (25 - 22) / (8 - 2)
m = 3 / 6
m = 0.5
Therefore, the rate of change is m = 0.5.
To find the initial value, we can use the formula for a linear function:
y = mx + b
Using one of the points in the table (let's use x = 2, y = 22):
22 = 0.5 * 2 + b
22 = 1 + b
b = 21
Therefore, the initial value is b = 21.
