Did that come with a image?
For this case we have that by definition, the slope of a line is given by:

Where:
and
are two points through which the line passes.
According to the figure we have to, the line goes through:

Substituting we have:

Thus, the slope of the line is -1.
Answer:

Answer:
The gradient of
is
.
Step-by-step explanation:
Geometrically speaking, the gradient of a curve is the slope of the tangent line at a given point of the curve. From perspective of Differential Calculus, the gradient is the first derivative of the curve. Let
, then the gradient of the curve is:
(1)
The gradient of
is
.
