Find the equation of a straight line: with slope -2 and intersecting the x-axis at a distance of 3 units to the left of origin.

Explanation

Let line AB intersect the X - axis at a distance 3 units to the left of origin.


At x axis y=0


`:.` Line AB cuts X axis at P (-3,0)


& slope of the line AB = -2, m=-2

We know that,
...
