Question

What is the relationship between the lines determined by these two equations?

3x + 6y = 8
y = 2x – 8

welshfella · Answer

rearrange the first equation so its in the form y = mx + c

welshfella · Answer

can you do that?

anonymous · Answer

parallel
       perpendicular
       neither parallel nor perpendicular
       they are the same line
are the options lol

campbell_st · Answer

the 2nd line is in slope intecept form

can you take the 1st line and make y the subject..?

welshfella · Answer

if you do the rearranging you'll see which one it is

anonymous · Answer

whaaaaat..

anonymous · Answer

Idgi..

welshfella · Answer

yes   y = mx + c is slope intercept form

campbell_st · Answer

ok... 3x + 6y = 8
       -3x           -3x       subtract 3x from both sides of the equation 
---------------------
                6y = -3x + 8

how do you get a single y on the left side of the equation..?

I've gotta go I'm sure campbell can help you

campbell_st · Answer

you will need to divide by a value in the next step
