Answer:
Helena is correct.
Step-by-step explanation:
The slope intersept form of the line is
y = m x + c
where, m is the slope and c is the intersept.
The point slope form of the equation is

So, if there are two points are given, the equation of line is found by the point slope form.
So, Helena is correct.
