Hi,

2x - 5y = 10   Or  y = (2/5)x - 2

Using the standard slope-intercept form for an equation of a line y = mx + b

  where m is the slope and b the y-intercept. m = 2/5

parallel Lines have identical slopes

New Line

 y = (2/5)x + b    | Using Ordered pair(x,y), Pt(0,-1) to solve for b

-1+=+%282%2F5%29%2A0%2B+b

   -1 = b

 y = (2/5)x -1    0r    2x-5y = 5
