Question

find the distance between the parallel lines 3x + y + 7 = 0 and 3x + y + 26 =0 ​

Answer 1

Answer:

Step-by-step explanation:

Just find a point say A on one of them & then find the perpendicular distance of the second line from the point A . Here we can see that a known on the 1st line is (0, 7) ( obtained by putting x =0 in the equation of the first line ). Now the distance of this point A(0, 7) from the second line is given by the formula ;
