Without any equality signs and a missing plus or minus sign the given expressions can't be solved as in an equation.

If you mean: y = 3x+3 then the slope is 3 and the y intercept is 3
Without an equality sign it is not an equation but if you mean y = 3x-1 then it is a straight line equation
If you mean: y = 3x+5 and y = 2x-7 then x = -12 and y = -31
Without any equality signs and a missing plus or minus sign the given expressions can't be solved as in an equation.
There can be no solution because there is just an expression - no equation nor inequality.
If you mean: y=3x-4 and the point (2, 1) then the perpendicular equation is 3y=-x+5

YES I THINK SO y=3x is a linear equation
This equation is incomplete, and to solve for two variables, you need two equations. So there is no "answer" for this.
If you mean: y = 3x+5 and y = 2x-7 then x = -12 and y = -31

y=3x+2 so the gradient or slope is 3
There is equation in the question. Limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals", "squared", "cubed" etc.
