    are you sure the matching equation is 6+2y=5?

    thats much better Okay so first you want to put it into slope intercept form which is y=mx+b

    okay so 2y=-6x+5 correct?

    start by subtracting 6x from both sides as it is a positive value which gives you

    2y=5-6x or 2y=-6x+5 then you divide both sides by 2 to isolate the y y=(-6x+5)/2 or y=-3x+(5/2)

    then i would get y=-3x+4 correct?

    correct because b is your 7 intercept and a parallel line has the same slope
