Answer 9

i think it is C

Answer 10

line 1=1/3

line 2=1/3

Answer 11

plz don't leave like the others did

Answer 12

I'm not leaving. I am calculating the equations of the two lines over at

http://www.mathportal.org/calculators/analytic-geometry/two-point-form-calculator.php

Answer 13

i don't know if i should put general form or not

Answer 14

I agree with the slopes of the two lines being 1/3.

Parallel lines have the same slope.

The next question is if the two lines are the same.

Answer 15

they are

Answer 16

i think they are

Answer 17

The form does not really matter. I usually go with y = mx + b out of habit.

Answer 18

Check to see if the y-intercepts are the same.

Answer 19

ok

Answer 20

it says y=1/3x+5

Answer 21

I got y-intercepts of 5 and 2. Did you get that?

Answer 22

Run that equation of a line calculator twice, once for each set of points.

Answer 23

they are on the same line

Answer 24

i don't think so.

Answer 25

Click here and look at the graphs of the two lines. They have the same slope but not the same y-intercepts so they are different lines but do not intersect.
