I need help finding the slope of the line
through (4, -1) and (-2, -1) Thanks!
Just plug
x1 = 4, y1 = -1,
x2 = -2, y2 = -1
into the slope formula:
y2 - y1
m = ---------
x2 - x1
(-1) - (-1)
m = --------------
(-2) - (4)
-1 + 1
m = --------
-2 - 4
0
m = ----
-6
m = 0
This means that the line is
horizontal. Here's its graph:
