Question

whats the distance between parallel lines when given y=-2x+1 and y=-2x+16

Answer 1

2x+y-1=0

2x+y-16=0

the distance between these two parallel lines,

I-16-(-1)I/√(2^2+1^2)

=15/√5

=5*3/√5

=3√5 (ans)


theory: two parallel lines,

ax+by+c1=0 and

ax+by+c2=0


the distance between these two lines is,


Ic1-c2I/√(a^2+b^2)

Answer 2

does that help?
