You cannot answer the question as posed. Not because you didn't bother to share the actual slope, although that in itself is problematic, but rather because there is no single unique equation of any line, hence the article "the" is inappropriate. What you can do is answer the question, "What is an equation of the line with the given characteristics?" Just use the point-slope form of an equation of a straight line, to wit:
where are the coordinates of the given point and is the given slope.
