The slope intercept form of the line is given by:

The point-slope form is given by:

Where,
m: slope of the line
b: cutting point with the y axis
(xo, yo): ordered pair that belongs to the line
For line A:
The slope is

The cut point with the y axis is:

Substituting values we have:
For line B:
The slope is given by:

Then, the equation of the line is:
