Answer 2

i think its a

Answer 3

yes that is correct, no solution:

Answer 4

\(\large\color{black}{ y = 3x - 4 \\ 9x -3y = 14 }\)


\(\large\color{black}{ y = 3x - 4 \\ -3y = -9x+14 }\)


\(\large\color{black}{ y = 3x - 4 \\ y = 3x-\frac{14}{3} }\)

Answer 5

they are parallel lines that never intersect.... good work.

Answer 6

if the x and y terms are a scalar multiple of each other, the lines are parallel, if the term on the other side of the = sine is also the same multiple, they are the same line.
