Nonlinear
Linear. The only power for the variables is 1.
y = 2x + 1 IS a linear equation!
Without an equality sign the given terms can't be considered to be any kind of an equation.
linear
It is linear.

No.
Linear. The only power for the variables is 1.
A nonlinear equation does not produce a straight line and the exponent is to the second power or more. x square plus 3y =5 is an example of a nonlinear equation.
If by d2 you mean d squared then it is non linear
5xy+4=9
It is linear in c and non-linear in d. If both c and d are variables, then it is non-linear.
y = 2x + 1 IS a linear equation!
