If f(2) = 3 and f'(2)=-1 find an equation of the tangent line when x = 2. How would I start this??

Question

anonymous · Answer

use the point slope formula 
$$y-y_1=m(x-x_1)$$ with 
$$x_1=2,y_1=3, m=-1$$

ahh, thank you. i got y=5-x?

anonymous · Answer

i didn't do it

anonymous · Answer

$$y-3=-(x-2)$$
$$y-3=-x+2$$
$$y=-x+5$$ yup

You need to learn order your equation by variable

anonymous · Answer

thank youu! your explanation was very helpful!

anonymous · Answer

the form is y = mx + b

I agree with Chlorophyll
even though AP calculus will give credit for the other formula.
They will even award credit if you just substitute and do not simplify
