Question

......Ax+By+C=0 is A(x1.....

Answer 1

Hi there,

The slope of the line Ax + By + C = 0 is

y = -(A/B)x + (-C/B)

Now,

We know that parallel lines have the same slope.

=>Slope of the other line=m= -(A/B)

Hence,

The required eqn. of the line is

(y - y1) = m (x - x1)

(y - y1) = -(A/B) (x - x1)

B(y - y1) = -A (x - x1)

Hence, A(x - x1) + B(y - y1) = 0.
