Lesson: Equation of a Straight Line: Parametric Form

Find the parametric equations of the straight line that passes through the point with direction vector .

Find the parametric equations of the straight line that makes an angle of with the positive -axis and passes through the point .

Write, in terms of , an expression for the horizontal distance between the two points.

Write, in terms of , an expression for the vertical distance between the two points.

Hence, write a pair of parametric equations which describe the line.

Find the coordinates of the point on the line which is at a distance of 4 from .
