Question

What is the equation of the line parellel to line L that passes through point (3, 3)?

Coordinates of line L are (-1, 3) (2, -3)

Answer 1

The slope of line L is


`= ( - 3 - 3)/(2 - - 1) = ( - 6)/(3) = - 2`
Since the line is parallel to L , it also has the same gradient,

The equation is


`y = - 2(x - 3) + 3`

`y = - 2x + 6 + 3`

`y = - 2x + 9`
