Question

Consider points P(2,1) and Q(2,5). Find parametric equations that describe points on PQ

Answer 1

The parametric equation will be x =2

Explanation:

We have given two points P(2,1) and Q(2,5)

We have to find the the equation of the line

The equation of line passing through two points is given by

`y-y_1=m(x-x_1)` , here m is slope

So
`m=(y_2-y_1)/(x_2-x_1)=(5-1)/(2-2)=(1)/(0)`

So equation of line
`y-1=(1)/(0)(x-2)`

x = 2

So the parametric equation will be x =2
