What is the slope of the line y=-2?
-----------
In slope-intercept form, y = mx + b
m is the slope.
----
y = -2 --> y = 0x - 2.

this is a horizontal line at y = -2.
slope equals change in the value of y divided by change in the value of x.
the formula is (y2-y1) / (x2-x1).
there is no change in the value of y, so the slope is 0.

a more interesting question is what is the slope of the line x = -2.

this is vertical line at x = -2.
the slope is undefined.
slope equals change in the value of y divided by change in the value of x.
the formula is (y2-y1) / (x2-x1).
there is no change in the value of x, so the slope is undefined because you are dividing by the change in the value of x which is 0.

here's a graph of y = -2 and x = -2.
the blue line is x = -2
the red line is y = -2

is slope-intercept form where is a slope and is y-intercept
You have which means where is a slope and
so, this is a horizontal line and slope is .
