Slope m is undefined?

write the equation of the line with slope m undefined and which passes throught the point (-4,5)

I’m pretty lost here… can someone explain how to do this?

A line whose slope is undefined is a vertical line. So, in this case, it is a vertical line which passes through the point (-4,5). The equation of the line is therefore x=-4.

x=-4, i think this the only case when m is undefined.

In general when x=k where k is any real number. Just neglect 5 it just makes you confused. If you check the graph of x=-4 it is a vertical line parallel to y-axis and passing through point (-4,5) and in general passing through the points (-4,k)
