Question

The distance between the two parallel lines L1: −7 x − 10 y=−4, L2: −7 x − 10 y=3 is ??????

Answer 1

7

Answer 2

no its not 7

Answer 3

L1: −7 x − 10 y=−4, L2: −7 x − 10 y=3
when x1=1 , y=-1.1 also
x2=1, y=-1
using the distance formula
d=sqrt[(x1-x2)^2+(y1-y2)^2]
d=sqrt[(1-1)^2 +(-1.1+1)^2
d=sqrt[0+(-0.1)^2]
d=sqrt[0.1=0.1 ans]

Answer 4

L1: −7 x − 10 y=−4,
L2: −7 x − 10 y=3

when x1=1 , y=-3/10
when x2=1, y=-1

using the distance formula
d=sqrt[(x1-x2)^2+(y1-y2)^2]
d=sqrt[(1-1)^2 +(-3/10-(-1))^2
d=sqrt[0+(-3/10-(-1))^2]
d=sqrt[((-3/10)+1)^2]
d=sqrt[((-3+10)/10)^2]
d=sqrt[(7/10)^2]
d=7/10
d=0.7
