Question

are the graphs of the line in the pair parallel?

y=1/3x+9
3x-9y=4

Answer 1

parallel lines have the same slope....so can you then tell me the slope of each line?

Answer 2

for y=1/3x+9 the slope is

1/3

Answer 3

can you tell me the slope of the second line....if you find out that it is the same as 1/3 then we know both lines are parallel because they have the same slope but if you don't get 1/3 then the lines are not parallel
