## anonymous 4 years ago Find the distance between the pair of parallel lines, y = -2x+1 & y = -2x+16. Choose one answer. a. square root of 45, or appx 6.7 b. 15 c. square root of 54, or appx 7.3 d. square root of 50, or appx 7.1

Distance between two parallel line is given by the algorithm $\left| c1-c2\div \sqrt{a ^{2}+ b ^{2}} \right|$

let me give you a hint, the answer will be in square root. :)

lol thanks tht narrows it down

wat does c1 and c2 stand for? what do i plug in there?

5. anonymous

your most welcome... and remember since both the lines are parallel the value of a and b in both the equation will always be the SAME!!!

c1 is the constant of the first equation and c2 s the constant of second equation.. since your using modulus,i.e,absolute value of it.. IT doesn't matter which equation you choose as first or second..
