Question

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

Answer 1

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.

Answer 2

tan 0 degree

Answer 3

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

Answer 4

in y = mx +c equation

Answer 5

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

Answer 6

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

Answer 7

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?

Answer 8

ok, thanks=)
