line m includes the points (-3, 3) and (-4,-6). line n has the same slope as line m and
a y-intercept of -2/3 the equation for line nin slope-intercept form.

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:
