Final answer:
To find the slope of the graph at a given point, you need to find the derivative of the function and evaluate it at that point. In this case, the derivative of the function x^2 - 4x / 24 is 1/3, so the slope of the graph at (5, 4/25) is 1/3.
Step-by-step explanation:
The slope of a curve at a point is equal to the slope of a straight line tangent to the curve at that point. To find the slope of the graph of the function at the given point (5, 4/25), we need to find the derivative of the function and evaluate it at x = 5. The derivative of the function x^2 - 4x / 24 is obtained by applying the power rule and the constant rule of differentiation. The derivative is 1/3, so the slope of the graph at the given point is 1/3.
