If you mean y = 4x+2 then it is the linear equation of a straight line
Without an equality sign the expression given can't be considered to be an equation.

y = 4x + 2 It has a slope (gradient) or 4. The slope/gradient of a linear function is simply the number in front of the x when the equation is in the form y=mx+b. (the coefficient of x).

If you mean: y = 4x-2 and y = x+13 then x = 5 and y = 18
Probably 4, but unfortunately, 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", "equals" etc. Also use ^ to indicate powers (eg x-squared = x^2).
