To find the slope of the line that passes through the points (2, 2) and (-1, 0), you can use the formula for the slope \( m \):
\[
m = \frac{y_2 - y_1}{x_2 - x_1}
\]
Where \( (x_1, y_1) = (2, 2) \) and \( (x_2, y_2) = (-1, 0) \).
Substituting the values in:
\[
m = \frac{0 - 2}{-1 - 2} = \frac{-2}{-3} = \frac{2}{3}
\]
So the slope of the line is \( \frac{2}{3} \).
The correct answer is **B. \( \frac{2}{3} \)**.
\[
m = \frac{y_2 - y_1}{x_2 - x_1}
\]
Where \( (x_1, y_1) = (2, 2) \) and \( (x_2, y_2) = (-1, 0) \).
Substituting the values in:
\[
m = \frac{0 - 2}{-1 - 2} = \frac{-2}{-3} = \frac{2}{3}
\]
So the slope of the line is \( \frac{2}{3} \).
The correct answer is **B. \( \frac{2}{3} \)**.
