Asked by Chandresh

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
Answered by Reiny
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
