Final answer:

To find the slope of the line tangent to the graph of f at point P, determine the endpoints of the tangent line and plug them into the equation to solve for the slope, a.

Step-by-step explanation:

The slope of a line tangent to the graph of a function at a point can be found using the formula mₜₐₙ = limₓ→ₐ f(x)-f(a)/x-a. To find the slope of the line tangent to the graph of f at point P, you need to determine the endpoints of the tangent line and then plug them into the equation to solve for the slope, a.

  1. Choose two points on the line, such as P and Q.
  2. Substitute the x and y values of the chosen points into the equation.
  3. Simplify the equation to find the slope, a.
