Answer explanation

4 is the coefficient because it is the number being multiplied by the variable (because it is shown in front of x)

x is the variable because it is a letter representing an unknown value

2 is the constant because it is not attached to a variable, therefore its value never changes (it will always mean add 2 no matter what x is)
