This lesson may help. As it explains, given a direction vector b for (a vector parallel to) a line L and a point a on the line, the line's equation is L = a + tb.
If <7, 2> is perpendicular to the line, what vector would be parallel?
Given that parallel direction vector and the point (2, -5) on the line, what then would be the equation of the line?
