Question

Which line(s) are parallel to y=3x+1​

Answer 1

Any line with a slope of 3

The line is in

y=mx+b

(m is the slope, b is the y intercept)

Therefore, in the line:

y=3x+1

3 is the slope

So, any line with a slope of 3 is parallel, because parallel lines have the same slope.

Hope this helps!

Answer 2

-3 since parallel lines have equal slopes
