How do u show that these 2 lines are parallel
L is y=3x-2
L*2 is 3y-9x+5=0

If two lines are parallel, then they have the same gradient.

Step-by-step explanation:

L is y=3x-2

L*2 is 3y-9x+5=0

The gradient for the first equation is 3

We need to rearrange the second equation and see if it has the same gradient as the first equation.

L*2 is 3y-9x+5=0

3y = 9x - 5

L*2 y = 3x - 5/3

As you can see, once you rearrange and simplify the equation, the second line has the same gradient as the first equation.

So that means these two lines are parallel

all but the second one

step-by-step explanation:

cuz that one goes over 180
