Tell whether the graphs of the two equations are parallel lines ...

(24) y = 8x-3, 8x + y = 3

(25) 2x + y = 5, - 6 + 2x = y

(26) 2x + y = 5, y = 0.5x - 3

(27) y = - 0.6 + 2, 5y + 3x = 8

(28) 8x + 3y = 9, 3y - 4 = 8x

(29) 10x + 2y = 7, 5x - y = 6

Parallel lines have the same gradient

the equation is y=mx+c ... where m is the gradient

24) y=8x-3 y=-8x+3 ... not parallel

25) y=-2x+5 y=2x-6 ... not parallel

26) y=-2x+5 y=0.5x-3 ... not parallel

27) y=-0.6x+2 y=-3/5x + 8/5

=-0.6x + 1.6 ... parallel

28) y=-8/3x+3 y=8/3x+4/3 ... not parallel

29) y=-5x+7/2 y=5x-6 ... not parallel
