Question

What is the slope of the line that passes through the points (3, -1) and (-1, -1)?

Answer 1

zero since the y coordinates are the same

Answer 2

0/4= 0 slope

Answer 3

o

Answer 4

slope formula

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

notice that when they multiply both sides
of that by (x2-x1)
they get something like this:

point slope formula:

y-y1 = m(x-x1)

Answer 5

zero
