Hi

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. 

Finding whether the pair of lines is parallel perpendicular or neither

5x+3y=10   OR   y = (-5/3)x + 10/3   m = (-5/3) Green Line

3x-5y=9    OR   y = (3/5)x - 9/5     m = 3/5

Lines are perpendicular (slopes are negative reciprocals, that is (-5/3)*3/5 = -1
