For this case we have that by definition, the equation of a line of the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
The slope of a line is given by:
We have that the line m passes through the following points:
So, the slope of the line m is:
Line n has the same slope so the equation is of the form:
We have as data that the y-intercept is . Thus, we have that the equation of line n is:
