To find the slope of a vector equation, you first need to express the vector in terms of its components. Typically, a vector equation can be represented in the form r(t) = x(t)i + y(t)j
, where r(t)
is the position vector, and x(t)
and y(t)
are functions of a parameter t
.
The slope of the line represented by the vector equation can be determined by taking the derivative of the functions with respect to the parameter t
. Specifically, you will calculate the derivatives x'(t)
and y'(t)
.
The slope m
can be found using the formula:
m = rac{y'(t)}{x'(t)}
This gives you the rate of change of y
with respect to x
, which represents the slope of the vector at a particular point. Make sure that x'(t)
to avoid division by zero, as this indicates a vertical slope.

For example, if you have a vector equation such as r(t) = (2t)i + (3t^2)j
, you would first compute the derivatives: x'(t) = 2
and y'(t) = 6t
. Then, you can substitute these into the slope formula:
m = rac{6t}{2} = 3t
This means that the slope of the vector equation varies depending on the value of t
.
