Slope of a polynomial function

[Cmertin]

Homework Statement

Slope of: y=.00002715x^2-.04934171x+44.18240907

Homework Equations

d/dx

The Attempt at a Solution

d/dx[.00002715x^2-.04934171x+44.18240907] = .0000543x-.04934171
This is the derivative (slope) of the function though it's looking for a numerical value. It is based off of data that was given. This function is the line of best fit of the data and I need to find the slope of the graph. If you could help me that would be great.

When you say "this function" I assume you mean the derivative function, y = .0000543x-.04934171. The slope of a line whose equation is y = mx + b is m, so the slope of your line of best fit is .0000543. The y-intercept of this line is -.04934171.
