That would give you the slope. You need the equation for the tangent line. The equation of a line through with slope m is .

Hello everyone
How would i solve the following
Find an equation for the tangent line to the graph of x+sin(y-2x)=1 at the point (1,2)
I did
1+cos(y-2x)(dy/dx)(-2)=0
then I did cos(y-2x)(dy/dx)=2
(dy)/(dx)=(2)/(cos(y-2x) so would I just plug in the value of x and y.
