Can someone help how to calculate the slope, tangent line and normal line? I'm lost on how I should code those three and I don't have much infor from clas how to code these 3.

The equation of a straight line is often stated in the form

y = m*x + b

You have calculated y0 (the value the equation will have at x0), and you have calculated m, so now you need to calculate b and put the result together in the form ytangent = m*x+b

The normal to a line at a point passes through the same line but has a slope 90 degrees different.
