The slope of a line is:

m=(y2-y1)/(x2-x1)

For example:

m=(-6-2)/(-4--4)

m=-8/0

m=+oo, it is undefined which means that this is a vertical line of the form:

x=-4  There is no slope, x=-4 is a vertical line.

"slope: undefined"

...

m=(-7--7)/(4--7)

m=0/11

m=0

This is a horizontal line of the form y=-7.

"slope: 0"
