To find the rate of change, we can use the formula:
\(\text{{rate of change}} = \frac{{\text{{change in y}}}}{{\text{{change in x}}}}\)
Using the table, we can see that when x changes from 1 to -3, y changes from 4 to 3.
So, the change in y is 3 - 4 = -1, and the change in x is -3 - 1 = -4.
Therefore, the rate of change is:
\(\text{{rate of change}} = \frac{{-1}}{{-4}} = \frac{1}{4}\)
To find the initial value, we can use the formula:
\(\text{{initial value}} = y - \text{{rate of change}} \cdot x\)
Using any of the given values in the table, we can substitute the values and solve for the initial value.
Let's use the first point (1, 4):
\(\text{{initial value}} = 4 - \frac{1}{4} \cdot 1 = 4 - \frac{1}{4} = \frac{15}{4}\)
So, the initial value is:
b = \(\frac{15}{4}\)
Therefore, the rate of change is m = \(\frac{1}{4}\), and the initial value is b = \(\frac{15}{4}\).
