Variable linear equation: y=ax+b, where a and b are any number , you can also called constant
and y and x are variable for example y= 2x+9, called linear equation.
can't be linear
x^2 (no exponents on variables)
2xy + 4 (can't multiply two variables)
2x / 4y (can't divide two variables)
√x(no square root sign on variables)
2x=c
Inequalities are the relations involving linear expressons. Equation is a special case of relation of inequality only.
for example
2x<3 such and expretion which doen't involve (=) sigh.
