Think of it in terms of the general equation for a line:
[tex]y=mx+c[/tex]
Where [tex]m[/tex] is the slope.
If you are given [tex]y=-2x-3[/tex] then, the -2 must be the [tex]m[/tex].
Therefore, the slope for the line is -2.
The slope of the line would be -2.
And remember. The one rule to find the slope of two given points is: y=mx+b
