To find the slope and y-intercept of the function defined by the points given in the table (X: 0 and 5, Y: 1 and -9), we can use the formula for slope \( m \):

\[
m = \frac{y_2 - y_1}{x_2 - x_1}
\]

Substituting the values from the table:
- \( x_1 = 0 \), \( y_1 = 1 \)
- \( x_2 = 5 \), \( y_2 = -9 \)

Let's calculate the slope:

\[
m = \frac{-9 - 1}{5 - 0} = \frac{-10}{5} = -2
\]

Now, the y-intercept is the \( y \)-value when \( x = 0 \). From the table, when \( x = 0 \), \( y = 1 \). So, the y-intercept is 1.

Therefore, we have:
- The slope is **-2**.
- The y-intercept is **1**.

Filling in the blanks based on the options given:
- The slope is **C -2**.
- The y intercept is **G (0, 1)**.
