what is the slope of the line where equation is y=-9? explain your answer, thanks

Question

anonymous · Answer

This graph is a horizontal line.  It thus has 0 gradient.
Also, if the line is in the form $$y = mx+c$$ then we know that the gradient is the value of m.  Now, if y = -9.  Then c = -9 and m = 0.

anonymous · Answer

tan 0 degree

anonymous · Answer

gradient and slope are the same thing. that is "m"

anonymous · Answer

in y = mx +c equation

thanks rspencer & mkuma36,but what is the meaning of the gradient? thanks again godbless

anonymous · Answer

In a two dimensional graph with x axis and y axis gradient or slopme is the value of m which is further equated as y/x

anonymous · Answer

The gradient is the slope of the line.  This means how steep it is or the following:
If I go right 1 unit, how far up do I go?
