![f(x)=2x^2-4x+1](https://tex.z-dn.net/?f=f%28x%29%3D2x%5E2-4x%2B1)
Substitute the values of x to the equation of the function f:
![x=-1\to f(-1)=2(-1)^2-4(-1)+1=2(1)+4+1=7\\\\x=2\to f(2)=2(2^2)-4(2)+1=2(4)-8+1=1](https://tex.z-dn.net/?f=x%3D-1%5Cto%20f%28-1%29%3D2%28-1%29%5E2-4%28-1%29%2B1%3D2%281%29%2B4%2B1%3D7%5C%5C%5C%5Cx%3D2%5Cto%20f%282%29%3D2%282%5E2%29-4%282%29%2B1%3D2%284%29-8%2B1%3D1)
Therefore we have two points (-1, 7) and (2, 1).
We can calculate the slope of line l.
The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Substitute:
![m=\dfrac{1-7}{2-(-1)}=\dfrac{-6}{3}=-2](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B1-7%7D%7B2-%28-1%29%7D%3D%5Cdfrac%7B-6%7D%7B3%7D%3D-2)

Step-by-step explanation:
Theoretical probability is what we expect to happen. For example, we do a test of flipping a coin. You know that its either gonna be heads or tails.
Experimental probability is what actually happens when we try it out. It occurs when we are doing an experiment and then something happens.
Hope this helps!
