To find the slope (or rate of change) between the two points \( A(2, 1778) \) and \( B(3, 2667) \), you can use the formula for slope:
\[ \text{slope} = \frac{y_2 - y_1}{x_2 - x_1} \]
Here, \( (x_1, y_1) = (2, 1778) \) and \( (x_2, y_2) = (3, 2667) \).
Substituting the values into the formula:
\[ \text{slope} = \frac{2667 - 1778}{3 - 2} = \frac{889}{1} = 889 \]
The slope is \( 889 \).
Therefore, the correct answer is: B 889/1 or 889.
