6. Which of the following equations would graph a line parallel to 3xy=7? a. y= 7x3 b. y= 3x+7 c. y= 7x+3 d. y= 3x

The theorem to use is that parallel lines that are not vertical have the same slope.

So, we need to take the given line: 3xy=7 and write it in slopeintercept form. 3x y = 7 3x 3x  y = 3x + 67 Multiply both sides by (1) y = 3x  7 So, of the options, which ones have a slope of 3?

Problem: y = 3x  7 > has slope of 3 Option A: y= 7x  3 > has slope of 7 Parallel lines have the same slope. So, Option A is incorrect.

Look again at the options.

@DrPepperx3 Which remaining option has a slope of 3? Look at the coefficient of the x terms.

y = mx + b where m is the slope and b is the yintercept y= 7x+3 Option C has a slope of NEGATIVE 7. The given line has a slope of 3. 3 and 7 are not equal. So, the given problem and option C are not parallel.

I see an answer option with a slope of 3. Do you see it? It looks a little different because no yintercept shows.

Be brave. Pick one.

Two options have been ruled out. One of the remaining two has a slope of 3. Which is it? See the attachment below.

The only logical one to me would be b

b. y= 3x+7 has a slope of 3. The given problem 3x  y = 7 ==> y = 3x  7 has a slope of 3. Parallel lines must have equal slopes. So, Option b is incorrect.

It is your work so you can choose to put b. If it were my homework, I would put d. y= 3x because y = 3x is a line with slope 3 so it is parallel to the given line.

I don't understand?

There is no way left for me to explain it other than the ways I have. If you don't know the theorem about parallel lines having the same slope, you won't know how to do the problem. You may know the theorem and have it confused with the slopes of perpendicular lines. Perhaps, you can ask a specific question. "I don't understand" does not give me insight into exactly where impasse is in your thinking. I'll attach the theorem here.
