Question

URGENT!!!! (FAN & MEDAL) PLEASE HELP.
Which of the following equations would graph a line parallel to 3x-y=7

Answer 1

y = 7x - 3
y = -3x + 7
y = -7 + 3
y = 3x

Answer 2

So 3x-y=7
Can you change it to slope intercept form?
Hint: it'll look like y=mx+b where m=slope

Answer 3

I think it might be y = 7x - 3

Answer 4

I know it can't be y = -3x + 7, because it intersects.

Answer 5

No its not y = 7x - 3

Answer 6

The answer is y = 3x I had to work them ALL out. :(

Answer 7

Yes. D is correct but you didn't have to work through all that.
So you have 3x-y=7
Add y to both sides. 3x=7+y
Subtract 7 on both sides. 3x-7=y
So the slope is 3.
And you know parallel lines have the same slope
So find the equation also with a slope of 3 which is D.y=3x
