I need help please. I dont have any idea

**drwls**, Monday, January 7, 2013 at 6:53amy = -(5/6)x for the first line, so the slope of your second (parallel) line is also -5/6. Its equation is

y' = -(5/6)x + C

C is the y-intercept of the second line.

You have to choose C so that y and y' are sqrt61 apart.

C is the hypotenuse of a right triangle with sides sqrt61 and (5/6)*sqrt61. Its value is sqrt[61 + (25/36)*61]

= sqrt[(61/36)*61] = 61/6

The line you want is

y' = (-5/6)x + 61/6

**drwls**, Monday, January 7, 2013 at 7:10amThere is a second line that is also a solution, below the first line

y' = (-5/6)x - 61/6
