Answer:
In this equation X is independent variable while Y is dependent variable.
Explanation:
Equation:
Y=10x+100
Independent variable in math:
A variable in an equation that may have its value freely chosen without considering values of any other variable.
Dependent variable in math:
A dependent variable is a variable in an expression, equation, or function that has its value determined by the choice of value of other variable.
According to above definitions Y is dependent of x. As we changes the value of x the value of Y changes.
For example if x = 1, Y will be 110.
And if x = 10, Y will be 200.
