the linear relationship is up four over one.
It is a linear relationship between x and y.
No solution. Multiply second equation by 3 and get 12x + 6y = 0 but already stated 12x + 6y = 9...

A linear relationship. Added: And a function.
It's a linear equation in two variables. When it's graphed, the graph is a straight line with a slope of 12 that intersects the y-axis at y=120.

You then have a linear relationship, or a direct variation. A straight line through the origin.
3x-15x-y= 45 -12x-y=45 -y=12x+45 y=-12x-45 Solution set: straight line, y-intercept=-45 and slope =-12
