Which of the following equations would graph a line parallel to 3x − y = 7? (1 point)

Question

Which of the following equations would graph a line parallel to 3x − y = 7?  (1 point)

anonymous · Answer

y = 7x − 3
y = −3x + 7
y = −7x + 3
y = 3x

anonymous · Answer

C?

anonymous · Answer

No. What is the slope of the line 3x - y = 7. Show me your work.

anonymous · Answer

Hint: WQrite the line in y = mx + b form, so m is the slope.

Give up?

owlcoffee · Answer

So let's see something about the Line equiation.
We Know it has this form:
$$y=mx+b$$
where m is the slope and b is the OY coordinate. 
By condition of parallelism, we know that the slopes must be the same!
So, what do we require for a line to be parallel to an other?

anonymous · Answer

y=3x+7?

anonymous · Answer

so its B..?

owlcoffee · Answer

yes! :)

anonymous · Answer

Excuse me, that is INCORRECT. It is NOT B.

anonymous · Answer

Our line has a slope of 3...so we want to pick from the choices, a line whose slope is 3.

owlcoffee · Answer

Oh my, I lost that -.
so yeah, the answe is y=3x

anonymous · Answer

Correct, y = 3x has a slope of 3!!!!
