### 8-6 Vectors and Parametric Equations

We can write an equation of a line by referencing a vector it is parallel to. This is called a Vector Equation

Vector equation: where t is a scalar.

1)Write a vector equation of a line passing through it is parallel to. This is called a P1 (1,4) and parallel to

2)Write a vector equation of a line passing through P1(3,-9) and parallel to

You can write vector equations by separating the horizontal and vertical components. This is a called a parametric equation.

Parametric Equation:

x=x1 +ta1

y = y1 + ta2

5) Write a parametric equation of y = and vertical components. This is a called a ½x + 7

4) Write a parametric equation of y = -4x + 7

How long is it until the second plane overtakes the first? and vertical components. This is a called a

How far have both planes traveled when the second plane overtakes the first?
