Question

find the equation of line passing through ( 1, - 2) and parallel to line 2x + y = 5​

Answer 1

Heya!!

Slope of two // lines are equal.

Equation of line passing through points ( 1 , - 2 ) and // to this line ( 2x + y = 5 ) is

given by

y- y1 = m ( x - x1 )

Here y1 = -2 , x1 = 1

And

m = -2

=>

y +2 = -2 ( x - 1 )

=>

2x + y = 0
