ratio of x and y coefficient of first = 2 : 5
ratio of x and y coefficients of 2nd = 4 : 10 = 2:5
but the constants are not in that ratio, so
you have two parallel lines
give the slop of each line and then determine whether two lines are parallel, perpendicular, or neither parallel nor perpendicular. 2x+5y=5, 4x+10y=0
