Answer:
The given equation is linear equation.
Step-by-step explanation:
The equation is -2x .
Then definations are as follows,
Linear equations = of form (max power of x is 1)
quadratic equations = of form (max power of 2)
cubic equations = of form (max power of 3)
exponential functions = of form ,
where a,b,c and d are constants.
In above case, a = -2 and x has max power of 1.
Thus, equation is linear.
