AQA Core 2 - if says to write an equation of the tangent to the curve...can I...

leave the equation in the form y=mx + c or does it have to be this y-y1 = m(x-x1) format?
Ok to leave it in the form y=mx+c unless the question specifically asks for ax+by+c=0.

If it doesn't specify, you can write it how you like.
